Abstract
A circuit for quenching an avalanche photodiode (APD) detector is disclosed herein. The circuit may comprise a discrete transistor configured to draw a quench current so as to enable a drop in a reverse bias voltage applied to the APD detector, and an integrated circuit connected to the discrete transistor, the integrated circuit including a plurality of circuit elements for controlling the reverse bias voltage.
