What's with the 2sk3018 MOSFET?
The 2sk3018 MOSFET is an unusual animal. It holds the top 30V spot, in my giant MOSFSET table. Its Crss = 4pF at 5V is the lowest, and its Ron(max) = 8 ohms, with 4V drive, is the highest, giving it...

AoE x-Chapters - 2x.11 BJT bandwidth, fT
Another x-Chapters section to read and think about. Here's 2x.11 where we take up BJT high-frequency bandwidth limits, Ccb, fT, etc. I've also included the two preceding sections, 2x.9 and 2x.10, but...

FFT query
I'm using a Microchip library FFT on a dsPIC witha time domain input, it all works splendidly and has done for some time. However, re-visiting the code with a bit more time to think makes me wonder...

Coupling of air core coils
Hi all, In the crystal radio world there is a contra-wound coil. Two windings, one wound clockwise and the other counter clockwise. This so the can be put in series or parallel. I'm trying to...

Paint for solar cell reflectors
If you use reflectors to direct more sunlight onto silicon solar cells you quickly run into a "wall" because the efficiency (and lifetime) falls as the temperature goes up. One YouTube video that used...

74HC74 oscillator simulation
IRL I don't think there's anything this configuration of the 'HC74 could do but oscillate; with an RC network from not-Q to not-CLR and D, CLK, and not-PRE grounded. But with these models from the...

Baroque BJT Digital Driver Stage
Had been meaning to finish this drawing for, hmm, guess it's about 8 years or so. Anyway, here it is: Not too useful to me at board level, just for how many parts it takes. Should be good for some...

Weird: GaN-Fet for dc/dc converters with s-parameters
< > < > Way to LTspice model: < > I'd like to abuse them as analog switches because of their low resistance (thermal noise) and low capacitance in a chopper amplifier. Any drawbacks I did not see? The...

OT: can you recognize a car make/model from an old film screencap
"Friends of Eddie Coyle", 1973. The yellow car in background is a '71 Road Runner. What's the black land-yacht on the right? My guess is second generation (61-64) Cadillac DeVille? Looks like someone...
