Abstract

The design results of a charge-sensitive amplifier (CSA) with a pseudo-differential output are presented. The CSA is intended for operation with signals of both polarities at the dynamic range up to 100 fC and parasitic detector capacitances up to 100 pF. In order to form a pseudo-differential signal, a first-order low-pass filter having a cutoff frequency of several hertz was used. CSA is designed in 180 nm CMOS process.

伪差分输出电荷敏感放大器

摘要

给出了具有伪差分输出的电荷敏感放大器（CSA）的设计结果。CSA旨在在动态范围高达100 fC的两个极性的信号以及高达100 pF的寄生检测器电容的情况下运行。为了形成伪差分信号，使用了具有几赫兹的截止频率的一阶低通滤波器。CSA采用180 nm CMOS工艺设计。
