摘要

介绍了一种用于硅单光子雪崩二极管(SPAD)的改进有源猝灭电路和线性计数电路。所提出的淬火电路快速紧凑。线性计数电路可以用一个小的电容实现10位大的计数范围，可以有效地减少像素的面积。双像素电路具有成本低、结构紧凑、计数范围大等显著优点，非常适合高密度SPAD阵列探测器。

A 10 bit analog counter in SPAD pixel

An improved active-quenching circuit and a linear counting circuit used for a silicon single photon avalanche diode (SPAD) are presented in this paper. The proposed quenching circuit is fast and compact. The linear counting circuit can achieve 10 bit large count range with a small capacitor, which can effectively reduce the area of pixel. Due to the significant advantages of low-cost, compactness and high count range, the two pixel circuits are very suitable for the high density SPAD array detector.
