摘要
Single-Photon Avalanche Photodiodes (SPADs) were fabricated and characterized in 150 nm CMOS technology. The SPAD is based on a p+/nwell junction with a p-substrate guard ring. In addition, a compact gain switched quantum well (QW) laser diode with a CMOS driver was used with the proposed SPAD for time-resolved diffuse optics measurements. The measured impulse response function (IRF) of the SPADs was similar to 50 ps at best. Two phantoms were measured to demonstrate the suitability of SPADs for time-resolved diffuse optics imaging (TRDOI).
