Abstract

PURPOSE:The DC combination of transistor composing low-frequency amplifier circuit is decreased as well as the bias between collector and base of transistor of differential amplifier is made stabilized. Thus, a stabilized amplifying action can be secured even under power source voltage fluctuation.
