Abstract
PURPOSE: To eliminate the need of a negative power source by grounding the gate terminal of an FET through a high resistance element with respect to DC.
CONSTITUTION: A gate bias resistance 10 having a high resistance RG is connected to a gate bias circuit 6. If the fundamental wave signal to be inputted from an input terminal 4 is zero or the signal level is low, the voltage between the gate and the source which is applied to one end A of the resistance 10 is equal to zero and the drain current is equal to the saturation drain current. A forward gate current IG flowing from the gate terminal of an FET 1 to the source terminal is increased according as the input level of the fundamental wave signal is raised, and a voltage equal to RG×IG is applied between the gate and the source of the FET 1. Consequently, since the negative voltage between the gate and the source is automatically impressed to the FET 1 by the resistance 10, the negative power source is unnecessary and a device is operated by a single positive power source.
