Hi All,
I use a CMOS inverter ( NMOS + PMOS , discrete), its output connects to a biopolar nmos' input, the inverter's output will be locked to 0.7V, what should I do...
the biopolar acts as a current source for LED driving.
Best regards, Boki.
CMOS inverter output to Biopolar

If it was bipolar you were using I'd say, add a resistor. But since you're using biopolar, you have to use a neuron.
Thanks,

Sorry, could you please decribe a little more ?
I don't know what is the neuron...
Best regards, Boki.
It's what you think with. :-) "bio" - biology, get it?
Sorry, boki, but when you serve up those fat straight lines we just have to take a swing at them.
p.s. Google is your friend in understanding English.
Thanks,

Google "resistor."

"Bipolar NMOS" is self-contradictory. You might mean a NMOS or bipolar or sink-only driver or source-only driver, though.
Then it's not an inverter. It's 0.7V source with zero impedance. Real drivers are source, sink, or source-sink.
Go outside, get fresh air, etc.
Figure out if it's a source or a sink. Figure out if it's bipolar (NPN, PNP) or MOS (PMOS, NMOS, DMOS, etc.)
Almost certainly your latest round of questions is answered in a early
70's TTL databook, Lancaster's CMOS cookbook, AOE in the section about interfacing to LED's/lamps, etc.Tim.
ROTFLMAO!

I love to cook with wine. Sometimes I even put it in the food.
still don't get it. I never study a "neuron" word in EE courses..

then ?
Thanks.... try the thinking way is another kind of learning...
Of course, study reference is very important.
Really? What kind of EE courses are they teaching these days in Taiwan? A neuron is just one element of a neural network.

Somebody who OBVIOUSLY never took a class from Carver Mead :-).
Not that I'm a Carver Mead devotee or anything. The instant I hear anyone talking about neural nets I tune them out!

typo is so funny? ..... = = .... ( save time to make something really productive that is very meaning)
It seems that it needs very large value resistor ( > 1000K ), am I right?
I take a simple try in PSPICE, I still ge 2.32v in inverter's output....

Hi Boki,
I've just spent half an hour Googling all the stuff you need, then I spent the next half hour reading it all for you. As we agreed some time ago, that's another $75 you owe me.

nmos isn't bipolar.
What are you talking about ?

Just watch out for the bipolar bears. ;-)
