Abstract

A compact readout circuit that can be integrated between individual single photon avalanche detectors (SPADs) is described. The circuit uses minimum sized transistors to both quench the avalanche process in the photodetector and integrate charge onto a capacitor to represent the number of detected photons. An additional transistor is integrated within the circuit so that the integration capacitance can be isolated from the source-follower output circuit before the integration time has elapsed. This device can be used by the user to control the relationship between the number of detected photons and the output voltage.
