چکیده :
The single-photon avalanche diode (SPAD) is a widely used single-photon detector in laser ranging applications, valued for its ultra-high sensitivity and ability to detect and image remote targets. SPADs are commonly employed in time-of-flight (ToF) sensors for 3D imaging and distance measurement. In this paper, an Active Quenching and Recharging (AQAR) circuit is presented, implemented in a 65nm CMOS process, to achieve a high photon detection rate within a short time. The results demonstrate that the quenching and reset times are 1.3 ns and 0.5 ns, respectively.
