GAIN_CONTROLLED_LOG_AMPLIFIER

Based on fact that gain of common-emitter fet stage is almost inversely proportional to emitter resistance, and resistance of let operating below cutoff is linear function of grid voltage. Can be used as agc amplifer and as multiplier.-Y. J. Lubkin, Gain Controlled Log Ampliler, GEE, 10:9, p 91.
