Abstract

PURPOSE:To operate an amplifier stably against power supply variations by moving the operating point of atransistor for driving and amplifying to the optimum value by attaching a bias circuit consisting of high resistors and diode connected to the input terminal of the transistor for the first stage amplifier.
