  • It may be becoming more and more esoteric, but this stuff is still definitely useful. In the last design I did, I used a PNP common base configuration to translate a 0-2.5V logic signal to a -5 to 0V-ish signal. Had to do a little brushing up on my transistor configurations, but a SPICE simulator does wonders for that! :-)

No public wish lists :(
