摘要 讨论了目前存在的基于米勒电容的采样/保持电路,在此基础上设计了一种简化形式。该电路利用简单的CMOS反相器代替米勒反馈电路中的运算放大器,在保证采样速度和精度的前提下,节省了面积。最后,采用TSMC公司的0.35μm标准CMOS工艺库对整体电路进行了性能分析和仿真。 This paper presents the existing sample / hold circuits based on Miller-Capacitance, then design a compact configuration, achieved by replacing the operation amplifier in the miller feedback circuit with a simple CMOS invert, saved area while promise the premise of the sampling speed and precision. The circuit is analyzed and simulated based on TSMC 0.35μm standard CMOS process.
