Abstract
A device including an optoelectric circuit that is configured to provide galvanic isolation between a first circuit and a second circuit is disclosed. The optoelectric circuit includes at least one non-inverting buffer and a metal semiconductor diode. The at least one non-inverting buffer is positioned between a collector of a phototransistor and an anode of a light emitting diode. The metal semiconductor diode is positioned between the collector of the phototransistor and the at least one non-inverting buffer.
