Silicon Avalanche Photodiode Active-Quenching Circuit
Abstract
Research has shown that actively-quenched silicon avalanche photodiodes (APD) can be successfully operated throughout the visible region. Two patented circuits exist which have been assembled as printed circuit board prototypes. A silicon hybrid of the most recent circuit, having two independent channels, has been demonstrated to operate at a photon counting rate in excess of 40 MHz. If the APD's are cooled a dynamic range approaching that of the average photomultiplier tube is possible. Two problems with the hybrid circuit have been identified and a way forward to eliminate the problems is proposed.
