ABSTRACT:
One end of each of five resistors is connected to each of the two ends and the respective intermediate points of a cascade of four depression-type FETs, while the other ends of the five resistors are provided with a predetermined voltage. This configuration fixes the source-drain potential of the four FETs. This fixing of the source-drain potential of the FETs permits stable application of a bias voltage for turning ON the FETs between the gate and the source each FET, so as to ensure the ON-OFF switching of the FETs.
