ABSTRACT:
A solid state photovoltaic generator circuit includes a source of activating radiation, an array of photodiodes responsive to the radiation, a switching device coupled to the photodiode array for responding to an electrical signal therefrom, and a high-impedance resistor which is made of substantially single-crystal silicon and is formed during the formation of the switching device. The fabrication of the circuit is thus significantly simplified and the resistor performance is stable over a wide range of operating temperatures.
