摘要
We present a novel gated operation active quenching circuit (AQC). In order to simulate the quenching circuit a complete SPICE model of a InGaAs SPAD is set up according to the I -V characteristic measurement results of the detector. The circuit integrated with a ROIC (readout integrated circuit) is fabricated in an CSMC 0.5μm CMOS process and then hybrid packed with the detector. Chip measurement results show that the functionality of the circuit is correct and the performance is suitable for practical system applications.
