Abstract / Description of output
A high resolution Time Correlated Single Photon
Counting (TCSPC) image sensor based on sample and
hold Time to Amplitude Converter (TAC)pixels and a global
ramp voltage is presented. The 256 256 array achieves an
8 μm Pixel Pitch (PP), 19:63% Fill Factor (FF), output voltage
range (0:7V) and time jitter of 368 ps at 10 fps employing
an off-chip 14-bit differential Analogue to Digital Converter
(ADC). A column-parallel flash ADCis also implemented,
allowing coarse 3-bin TCSPC histogramming at 4 kfps for
video rate fluorescence lifetime imaging.
