缩放半导体传感器器件时的一个重要考虑因素是它可能对噪声性能产生的影响。总信噪比可以通过增加传感器尺寸或者通过平均来自两个或更多个较小传感器的信号来提高。在传感器系统的设计中，并不立即清楚哪一个是最好的策略。在本文中，我们提出了一个详细的理论和实验研究的基础上，三个不同的传感器阵列，表明一个小的独立传感器的阵列总是比一个大的传感器相同大小的噪音少。(C)2019作者爱思唯尔有限公司出版
An important consideration when scaling semiconductor sensor devices is the effect it may have on noise performance. Overall signal to noise ratio can be improved both by increasing sensor size, or alternatively by averaging the signal from two or more smaller sensors. In the design of sensor systems it is not immediately clear which is the best strategy to pursue. In this paper, we present a detailed theoretical and experimental study based on three different sensor arrays that show that an array of small independent sensors is always less noisy than a large sensor of the same size.
