基于成像系统应用的低噪声Si-CMOS读出电路设计

Design of Low Noise Si-CMOS Readout Circuit For the Imaging Applications

本文分析了读出电路的工作原理,基于相关双采样(CDS)技术,提出了一种改进的电容跨导放大器(CTIA)结构的Si-CMOS读出电路,并详细介绍了电路结构及工作过程。

The operational mechanism of readout circuit are analyzed and methods for decreasing noises are presented in this paper. An improved readout circuit with CTIA is put forward, and the correlated double sampling technology is used. The structure and operational mechanism of the circuit are detailed.
