difference between bipolar and mosfet

I can only apologize. Sadly, It's all too easy to fall into the trap of talking down to one's inferiors. Especially when the ability-gulf is so wide. I don't wish to appear patronizing, but in your case, it's unavoidable. HAND.

Ridiculous twaddle.

Once again your comprehension problem raises its ugly head. I think it was Charles Peguy who once said: "He that does not bellow the Truth when he knows the Truth is the accomplice of liars and forgers." I am no such accomplice. I *do* bellow the truth. The "stealth" I mentioned relates solely to the *means* by which the Truth is disseminated. I don't compromise by publishing innuendo; I simply obscure myself as the source, that's all. And even that only to preserve my liberty and livelihood in this modern era of suppression and Liberal bigotry.

See above, Bonehead.

The change in drop may only be 200mV., but when you're talking about an initial level of only IRO 650mV., I'd say that amounts to a large drop alright! It's all relative. You *do* realize that one diode drop at room temperature is only just over half a volt, don't you, Junior?

Lectures from someone who doesn't even know how a BJT works, I don't need. My youngest boy of 11 knows more about transistor theory than you do, Junior. Plus I'll wager from your postings that you're a good few years older than he is. More effort required!!

i don't remember ever getting involved in this thread, i was just enjoying the bickering that was taking place. i don't need to open text books on Silicone theory, let see if i can remember anything from years ago. 4 electrons for each (silicone)which bond to 4 other atoms, N Dope material that has 5 electrons which allows one to move freely and the P material that has 3 electrons which creates a hole, or more like a void etc..(poorly worded i know) i don't remember the compounds used now for the N an P doping/but phosphorus, arsenic, boron,gallium and some others i can't remember. all i remember is that they need > 4 electrons for the N dope and < 4 for the P dope. etc.. the above maybe a little vague because i don't sit and study physics and have no need to keep that at the top of my head every day. SO what ever, transistor theory is basic to me , i understand and know how to work with it and i guess that is all that matters. Have a good day.

Ummmm...I would like to point out that the "relative" in most relevant cases here will mean "with respect to other DC voltages in the circuit," NOT with respect to the magnitude of the B-E drop itself. For the purpose of most DC biasing calculations, f'rinstance, assuming the B-E junction to be a constant drop of ~0.6-0.7V works just fine, thank you very much. You can go back and refine things if you like, later on, but you'll generally wind up with results far closer to reality than the accuracy you can count on in the component values, supply voltage, etc.. So what's all the hubbub, bub?

Why do I get the impression that the "works and plays well with others" box was rarely checked on your report card? :-)

--- Now that I've explained it to you you can pretend you knew it all along?

Here's a little something (Positively Fourth Street) from Bob Dylan you might identify with: (Pay particular attention to the sixth, eleventh, and twelfth verses.)

You got a lotta nerve To say you are my friend When I was down You just stood there grinning

You got a lotta nerve To say you got a helping hand to lend You just want to be on The side that's winning

You say I let you down You know it's not like that If you're so hurt Why then don't you show it

You say you lost your faith But that's not where it's at You had no faith to lose And you know it

I know the reason That you talk behind my back I used to be among the crowd You're in with

Do you take me for such a fool To think I'd make contact With the one who tries to hide What he don't know to begin with

You see me on the street You always act surprised You say, "How are you?" "Good luck" But you don't mean it

When you know as well as me You'd rather see me paralyzed Why don't you just come out once And scream it

No, I do not feel that good When I see the heartbreaks you embrace If I was a master thief Perhaps I'd rob them

And now I know you're dissatisfied With your position and your place Don't you understand It's not my problem

I wish that for just one time You could stand inside my shoes And just for that one moment I could be you

Yes, I wish that for just one time You could stand inside my shoes You'd know what a drag it is To see you

--- And yet, "knowing" all that you chose to make this unqualified statement earlier on?:

"You *do* realize that one diode drop at room temperature is only just over half a volt, don't you, Junior?"

I'd say that sentence speaks volumes about your competence.

---

--- Sure I do. they were after copper oxide and selenium, but before silicon.

---

--- An experiment can't be dumb, [stupid] but the experimenter can. That's why I suggested that _you_ start with the pot cranked to maximum resistance.

---

--- I'd have to look it up to find out, but the subject isn't diodes with a negative resistance characteristic, it's just plain ol' garden variety rectifiers.

---

--- Hmmm... Where have I heard _this_ before?:

"You *do* realize that one diode drop at room temperature is only just over half a volt, don't you, Junior? "

---

--- Fuck you. Respect is earned. I'll do what pleases _me_, not walk on eggshells the way you'd like me to in order to make your life more convenient for you.

---

--- Ignorance isn't exposed by the use of "foul" language, it's exposed by posting material full of errors as you are wont to doing.

Semantics again...

[snip more bilge]

No really??? Goodness me!

I don't have to do this stupid experiment. Any half-competent engineer will know that the barrier height potential of the Schottky will be

*much* lower than a 'comparable' silicon diode. You're talking maybe 270mV. Germaniums likewise (but you won't remember germanium diodes, Junior). Shall we perform your dumb experiment with other types, too? How about a back diode? can you get any lower than that?

If I learned anything new from *that* experiment I'd give up electronics altogether tomorrow.

There's nothing wrong with my diode theory, Junior. I'd probably completed my studies before you were even born. Don't talk back to your elders and betters. Learn some respect.

Sorry, no compliment intended. I infer you're older in view of your cockiness and the foul language you readily resort to each time your ignorance is exposed. HAND, Junior!

I don't know. Ask Fields. He's the one with the problem! I'm well aware that diodes are used to drop voltage in many circuits. The technique crops up frequently in the drives to Class AB and B amplifiers. It has shortcomings, however and I'd never suggest a newbie make use of it.

Correct. No one likes an achiever, but I never gave a damn about popularity. My coursework always came first - like myself at the top of the class.

[bafflement] None of which is applicable here. Thank God they don't write 'em like that anymore.

I'd say your remark simply shows once again that you either don't read, or don't understand, what is written for your consumption. (That much was obvious from your tedious exchanges with Kevin). You ought to know perfectly well that my earlier comments were in relation to a typical silicon diode with a Vbe of 0.6-0.7V. Allow me to quote from an earlier post of mine made 2 days ago:

"Really? So what is it you're taking issue with? Taken as a generalization for most silicon diodes I can't see real problem with it."

I thereby made it perfectly clear I was *not* including the more exotic varieties of diode in my remarks!

So you did a little research on the Web, uh, Junior? Well it's about time you absorbed something for a change. Keep it up!

How very thoughtful. And there was I about to connect it straight across a lead/acid battery...(forward-biased, of course).

Indeed. So why all this nonsense about Schottkys?

Your ignorance is only exceeded by your persistence, I'll grant you that.

Fine; that's the way it is all too often with you kids today. I blame rap music for turning their heads.

ROTFLMAO!! That's rich, coming from you of all people.

"FOAD" isn't a swear word; it's an acronym containing one. I wouldn't stoop so low as post the 'F-word' in a public forum. And from what I've read of Mr. Thompson's contributions, he makes pretty frequent use of the acronym himself. "Honi Soi Qui Mal Y Pense" as they say in France!

I understand allusion perfectly, Junior. What I don't understand is why some spotty-faced, high-school-reject jerkoff like you would want to post lyrics from a song that so clearly flags up his own self-loathing. You're so full of yourself in your postings, yet you cite self-disparaging lyrics that basically show you up to be the sad, sorry-assed, sack of s**t loser/loner that you really are. That's quite an admission in a world-wide public forum!

I appreciate you're only trolling here, Junior, but if you do a little research on the Web you'll find that such batteries are comprised of a series of lower value cells. You just place them in series and stick 'em in one box and voila: you have the required voltage. BTW, I don't appreciate sarchasm from spotty-faced, high school rejects, so cut the crap and show some respect, boner.

You can't have it both ways, Junior. Let me repost that quote of mine that you're so fond of citing in this thread:

Now, please tell us which common-or-garden, run-of-the-mill, general-purpose silicon diode *doesn't* have a drop of "just over half a volt" at room temperature??

Yes, I do. As is clear for all to see. Sadly, I don't have Kevin Aylward's degree of persistence, however. I find it exceedingly tiresome to have to repeat, ad nauseam, the kind of entry-level basics that my youngest son was acquainted with a good

3 years ago.

Certainly not. I know the song you quoted, but like everything else Dylon wrote, it's an overvalued crock of s**t. I'd wager that in truth you get off on the likes of Eminem, 50 Cent, Tupac and Dr. Dre. That's where you get your dire attitude problem from, IMO.

Why wouldn't anyone want to be successful and erudite? Why wouldn't anyone want to be able to piss all over jerks like you in debates? Why wouldn't anyone want to be able to see through the smoke and cut to the quick? My youngest (like his siblings) is going to grow up to be just like his dear old dad - a chip off the old block - whether he likes it or not. It's for the best. The alternative is too horrific to contemplate. It's just a tragedy that I can't save him from exposure to the poisonous, soul-destroying influences of the rap music culture that you so clearly embrase and embody.

I'm not familiar with that term and I shudder to think what it might mean, coming from a foul-mouthed young hudlum like you. Kindly preserve my igorance!

No, I'm simply maintaining my place on the moral high ground.

We don't all live in a free country, Junior. My right to say what I believe has been proscribed by the stinking British government. Just think yourself lucky that you're alive and well in a country that's only too happy for you to sit in front of your dumb TV shows, jerking off at all those topless models.

--- Boner??? Is that supposed to be some kind of insult where you come from? It doesn't make any sense as an insult here, and I'm pretty sure it's not supposed to be a compliment, so unless you care to explain it, it'll fall on deaf ears. Even if you do explain what you mean though, it probably won't make much difference since most of what you say is bullshit, anyway. Case in point, that 9V claim of yours.

With a terminal voltage of about 2.041V,

There's no way you can get 9V out of any number of lead-acid cells no matter how you choose to arrange them or what kind of a box you put them in, LOL! Now, you can't get much more basic than batteries, and you obviously don't know what you're talking about even there, so you're running at about what so far? Zero for two?

---

--- Rather than just handing you the information, I think it would be a good thing if you got off of your fat, lazy, ass and performed that little experiment I suggested and then post what you find. I mean, after that battery fiasco aren't you even interested in finding out whether what you think you know about diodes is true?

--- Or, obviously, his acumen.

If you did you would have noticed that if my persistence is >0, then at the lower limit of persistence (which I've been exercising so far) my ignorance would be zero.

We _all_ lost a lot of lives to "save the world", and a little luck here and there helped, but it wasn't _all_ serendipetous.

Yeah, but I'm not talking about cheating and loading the battery down
so hard that its internal resistance drops 3V (if it's a 12V battery).

But, I could be wrong, so what did you have in mind?
Reply to
John Fields

So you're saying I can't get 9V from a lead-acid battery?? And I'm not talking about relying on any type of rheostat or voltage-dropper here. You're saying it's impossible for me to get 9V out of a lead-acid battery by itself alone? Are you serious?

IOW: "Holy crap! Miles has boxed me into a corner here so rather than admit to the fact that I was wrong all along I'll try another diversionary tactic." Look, Junior, your 'experiment' simply demonstrates that the barrier height potential of the Schottky is around half the level of a regular silicon diode. You OTOH seem to think they're the same thing and therefore interchangeable, presumably. I wonder why they bother to make Schottkys then?

I'm certainly not used to having my opinions questioned by a snotty-faced school kid, that's for sure. You gotta lot of nerve, Junior. Most good folks simply accept what I tell them and go away wiser for it. Not so in your case, however. :-(

You don't like my personality? Sounds like sour grapes on your part, Junior.

I haven't seen any evidence of that yet...

I've made a good living from my technical skills over the years, Junior. People don't pay you good money for being a bonehead. Now, isn't it about time you stopped jerking off in front of that computer and went back to high school?

Certainly not. it's beneath my dignity.

Shame you can't kick them out of *here* as well!

Britain wasn't occupied in either WW so I don't know where you got that lofty idea from. And 'you' were quite happy to sit on the sidelines and twiddle your thumbs until the Nips blew Pearl Harbor all to hell. If that incident hadn't forced your hand after more than 2 years of inaction, you'd probably have stayed out of WW2 altogether and left us to get on with it alone.

Correct. To my very great intellectual cost! I wonder if entering into discourse with the ignorami can eventually result in organic brain damage? :-/ Time will tell.

I've heard of splitting hairs but this is ridiculous, you insolent young pup. You are saying both diodes are essentially the same and therefore interchangeable. I'm saying no way; certainly not for all applications at the very least.

You want to be careful with those long words, punk; they'll aggravate your acne.

I don't give a fig for being revered. That's a concern solely for lonely, lame-ass losers with a fragile sense of self. Ring any bells?

You gotta try harder....

Once again, you misunderstand. That's what comes from listening to too much rap music. I can't communicate on the same level as young punks like you; that's all there is too it.

Not at all. They beat a path to my door. I don't even have to advertise.

Translation: "My ass can't take no mo' whuppin' from this Miles guy! I need to bail out - and fast!!!" ROTFLMAO!!! BTW, if this "development work" you have in mind is to make your dick bigger, you'll find the Swedes make the best devices. ;->

That'd probably be safer. We're fed up with getting shot-up by your gung-ho, narcoleptic troops in these all-too-frequent "friendly-fire" incidents. :-(

Nonsense. We had the largest navy in the world at the outbreak of WW1. And the Germans never wanted to wipe us out, anyway. They were our biggest admirers! Hitler was a great anglophile; it must have broke his heart to bomb us.

So what's your excuse for invading Vietnam? Or Korea? Or Iraq (to name but a few) for that matter? I don't recall any of those countries attacking your lame ass.

I possess none. I must add one point, though: when *your* ass is on the line, *we* are just as keen to jump in and help you (for what its worth with what's left of our vastly downsized armed forces). We don't forget past favors and there's still a lot of affection here for you bastards.

ROTFLOL! I can't help but like you in a strange kind of way. You remind me of the son I never had - THANK GOD!!! ;->
