Abstract
A single-photon receiver is presented. The receiver comprises two SPADs that are monolithically integrated on the same semiconductor chip. Each SPAD is biased with a substantially identical gating signal. The output signals of the SPADs are combined such that capacitive transients present on each output signal cancel to substantially remove them from the output signal from the receiver.
