Abstract

PURPOSE:To improve the linearity by making use of the backward rectification detection of the gate electrode. CONSTITUTION:Impedance circuit network 13 is inserted to the gate bias circuit of FET amplifier 1, and at the same time the voltage of bias power source 8 is set to the value near the starting of the backward rectification current of the FET. When the amplitude of the input signal is small, the gate current is minute. Thus no effect is given substantially to the operation of FET5 due to network 13. And with increase of the input signal, the gate current starts to flow to cause the voltage drop across impedance Z1. This voltage drop is caused in the direction where the gate bias voltage is made shallower, and accordingly the drain current increases to cause increment of the amplifier output as well.
