We report on the design and characterization of a novel time-resolved image sensor fabricated in a 130 nm CMOS process. Each pixel within the 32x32 pixel array contains a low-noise single-photon detector and a high-precision time-to-digital converter (TDC) ...
Imaging techniques based on time-correlated single photon counting (TCSPC), such as fluorescence lifetime imaging microscopy (FLIM), rely on fast single-photon detectors as well as timing electronics in the form of time-to-digital or time-to-analog convert ...

Random telegraph signal (RTS) behavior is reported and characterized in the dark count rate of single-photon avalanche Diodes (SPADs). The RTS is observed in a SPAD fabricated in 0.8-mu m CMOS technology and in four proton-irradiated SPADs designed and fab ...

By ignoring events originating in noisy areas of a position-sensitive single-photon avalanche diode (SPAD), reduction of noise from fixed-position defects is experimentally shown. Additional experimental results from a position-sensitive SPAD integrated in ...
