Abstract

PURPOSE:To obtain an amplifier circuit which is from fluctuation of the DC bias point of the output at the switching time, by feeding through switching from one constant current source to the first differential amplifier (positive feedback, oscillator action ) and the second differential amplifier (negative feedback, amplifier action).
