Abstract
PURPOSE:To perform stable class ''B'' operation, by providing a polysilicon resistance in parallel to a transistor equivalent to a feedback resistance. CONSTITUTION:Even in case of a drop in potential at point (b) due to a current flowing through leak resistance 9, a current flows from point (a) to point (b) via a polysilicon resistance serving as a feedback resistance. Even if the source-drain resistance of FET4 as the feedback resistance increases owing to back gate effect, the potential drop at point (b) can be supplemented. Further, providing coupling capacitor 7 between two FETs 1 and 2 constituting an inverter forms the loop of FET1 and FET3 for the feedback resistance, and consequently even if the power source voltage fluctuates, the potential at the gate bias point of FET1 follows up the fluctuations, so that stable oscillation can be carried out.
