One of the most predictable non-linear elements commonly available is the bipolar transistor. The relationship between collector current and emitter base voltage is precisely logarithmic from currents ...

Download this article in PDF format. Logarithmic amplifiers with their log functionality are useful for compressing wide dynamic-range signals whereby the measured quantities are in decibels (dB).

Function generators (FGs) are measurement instruments in the category of waveform sources. They grew out of both a need for a versatile source of multiple waveshapes and from some interesting analog ...

I take my hat off to engineers that know transistors in every intimate detail. The other day, searching for something else completely, I came across Nat Semi (now TI) document LB-38 ‘Wide range timer’ ...
