The performance of the current-assisted single-photon avalanche diode (CA-SPAD) can be demonstrated to its full extent when used in conjunction with an active quenching circuit (AQC) located on the same chip. Counting rates, photon detection probability and single-photon timing resolution improve substantially as is evidenced by measurements in this paper. It is also demonstrated that a PDP of 20 % at 940 nm can be reached, making the CA-SPAD one of the best performing front-side illuminated (FSI) CMOS SPADs for near-infrared (NIR) operation.
