Standard log-amp design. Modified so both negative and positive signals will be processed.


Standard Log Amp, but with both PNP and NPN transistors in parallel in the feedback loop so both positive and negative signals will be processed. Useful for seeing millivolts with precision, yet still pass volt level signals.
