Abstract

In this paper, a simple analytical model for the Gaussian’s peak response part of the timing jitter of single photon avalanche diodes (SPADs) is proposed using Fourier series in the multiplication time calculation. The multiplication time characterizes avalanche multiplication process speed in which low multiplication time suggests a swifter response time and a higher avalanche speed. This paper presents an analytical solution which results in a more accurate multiplication time. The model is verified for SPADs implemented in 0.15 and 0.18 μm standard CMOS process, and the accuracy of the proposed analytical method in full-width at half-maximum (FWHM) calculation is improved by 25% and 5% with respect to the numerical model, respectively.

SPAD时序抖动的傅立叶级数建模

本文利用傅立叶级数对单光子雪崩二极管(SPADs)的时序抖动的高斯峰响应部分进行了乘法时间计算，提出了一个简单的解析模型。乘法时间表征雪崩乘法过程的速度，乘法时间越短响应时间越快，雪崩速度越快。本文给出了一种解析解，可以得到更精确的乘法时间。在0.15 μm和0.18 μm标准CMOS工艺中实现的spad上验证了该模型，结果表明，该分析方法在半最大全宽度(FWHM)计算中的精度比数值模型分别提高了25%和5%。
