A monolithic optical receiver containing four single-photon avalanche diodes(SPADs) fabricated in 0.35-μm high-voltage (HV) CMOS is introduced and compared with two 4-SPAD receivers realized in pin-photodiode CMOS belonging to the same process family. This HV-CMOS SPAD receiver achieves sensitivities of −55.1 dBm at 50 Mbit∕s and −52.0 dBm at 100 Mbit∕s, both with digital processing, a bit error rate (BER) of 2 × 10⁻³, and return-to-zero coding using a wavelength of 642 nm. Also at 143 Mbit∕s, this BER is achievable. This receiver
is especially interesting for applications in which low light intensities can be expected, such as quantum key distribution, optical communications from deep space, and visible light commu-nication for short-range consumer applications.
