Abstract
An electronic device disclosed herein includes a single photon avalanche diode (SPAD) configured to detect an incoming photon and to generate a first pulse signal in response thereto. Pulse shaping circuitry is configured to generate a second pulse signal from the first pulse signal by high pass filtering the first pulse signal. The pulse shaping circuitry includes a transistor drain-source coupled between a first node and a reference node, and a capacitor coupling the first node to an anode of the SPAD.
