Figures of merit for CMOS SPADs and arrays

SPIE Proceedings, 2013
SPADs (Single Photon Avalanche Diodes) are emerging as most suitable photodetectors for both single-photon counting (Fluorescence Correlation Spectroscopy, Lock-in 3D Ranging) and single-photon timing (Lidar, Fluorescence Lifetime Imaging, Diffuse Optical Imaging) applications.

A Differential SPAD Array Architecture in 0.18 μm CMOS for HDR Imaging

International Symposium on Circuits and Systems, 2022
We propose a scalable architecture for a differential single-photon avalanche diode (D-SPAD) array which generates measurements based on differential time-of-arrival in lieu of absolute time-of-arrival.

Compact CMOS Analog Counter for SPAD Pixel Arrays

IEEE Transactions on Circuits and Systems II: Express Briefs, 2014
In this brief, the design and experimental characterization of a compact analog readout circuit for photon counting is presented. A test chip, including a 20 × 20 counter array, has been manufactured in a standard 0.35-μm CMOS technology. The circuit delivers an output voltage proportional to the input pulse count, with a programmable voltage step. The
