Abstract
PURPOSE: To increase the dynamic range of the rear amplifier step as well as to obtain an easy-to-be-integrated controller, by giving a cascade connection to the differential amplifier step for gain control use as well as to the differential amplifier which supplies the input signal and then providing an equivalent constant current circuit to the common emitter circuit in the input differential amplifier step.
