FET serves as nonlinear element in fastacting instrumentation circuit han-dling wide range of signals. R1 and R2 attenuate input signal so FET input is less than 25 mV for inputs up to 2 VRMS. Article covers design and performance. Gain is almost linear with gate voltage of FET，-R D Pogge,Designers'Guide to：Basic AGC Amplifier Design、EDNMagazine，Jan，20、1974、p 72-76
