Abstract :
A new high-speed and controllable single-photon counter system is proposed in this paper for real-time brain imaging. It includes an avalanche photodiode (APD), a preamplifier and a mixed quench-reset circuit. In order to reduce the power consumption and after-pulsing, and also increasing the sensitivity and fill factor, the photon-counting front-end circuitry is integrated on-chip with APD using standard CMOS technology. This miniaturized system offers an ultra-fast quench-rest time (~few ns) with a low-power consumption (<;1mW).
