  • Control Of Amplification And Gain Control (AREA)

Abstract

PURPOSE: To obtain an AGC circuit which can decrease the distortion caused by the discord of the characteristics of the different polarity transistors, decrease the number of the terminal and can be suitably applied for a monolithic formation, by using in common both the output terminal of AGC and the input terminal of the rear-stage differential amplifier.
