  • Control Of Amplification And Gain Control (AREA)

Abstract

PURPOSE: To make broader the region of gain control, by picking up the output current with the synthesis of the differential output signal of a differential amplifier, superimposing this current to the fixed DC current, and controlling the level of output current.
