  • Control Of Amplification And Gain Control (AREA)

Abstract

PURPOSE: To obtain the gain control circuit with excellent performance, on which not only the compensation range is wide against the variations of the characteristic of diode causing the leakage of the control signal, and the linearity is good, but also the power consumption for the compensation circuit is a little, by installing the differential amplifier.
