Abstract
A transistor-bias voltage stabilizing circuit comprises a current saturating resistor connected in series to the output of an FET, the gate bias voltage of which is to be stabilized and a capacitor connected in parallel to the current saturating resistor. The transistor-bias voltage stabilizing circuit may comprise a voltage detecting circuit and a negative-feedback circuit connected between the input and output of an FET, the gate bias voltage of which is to be stabilized.
