Abstract

A 1024 × 8 single photon avalanche diode (SPAD) based
line sensor for time resolved spectroscopy is implemented in
0.13 μm imaging CMOS with 23.78 μm pixel pitch at
49.31% fill factor. The line sensor can operate in single
photon counting (SPC) mode (65 giga-events/s),
time-correlated single photon counting (TCSPC) mode (194
million events/s) or histogramming mode (16.5
giga-events/s), increasing the count rate up to 85 times
compared to TCSPC operation. This performance is enabled
by a 512 channel histogramming TDC with 50ps-6.4ns/bin
zoomable time resolution.
