ABSTRACT:
A self-biased MOSFET with suitably biased substrate is used as one of the rectifiers in a rectifier circuit for converting a-c power to d-c power for application to a monolithic integrated circuit of which the rectifier circuit is a part. This avoids the parasitic transistor action which would accompany the use of an isolated pn semiconductor junction, which parasitic transistor action undesirably discharges a storage capacitor connected across the output of the rectifier circuit.
