摘要
为提高生物微传感器的探测灵敏度,设计了一种低噪声的生物微传感器CMOS读出电路,提出了一种新型的相关双采样(CDS)电路,对读出电路的噪声进行抑制。在0.6μm CMOS工艺下,用Spectre仿真器对该电路进行了模拟,仿真结果表明,采用相关双采样的CMOS读出电路使传感器的输入输出转换具有良好的线性关系。
A CMOS readout circuit for biosensor that used a new Correlated Double Sampling （CDS） circuit was designed. The CDS circuit makes biosensor possible to obtain high sensitivity and low noise features. Simulation was carried out on a 0. 6μm CMOS process by Spectre simulator. The simulation results showed that a good linear relation between input and output of the biosensor has been obtained by using CMOS readout circuit based on CDS.
