| 摘 要： | This paper presents and experimentally verifies an optimized design procedure for a CMOS low noise operational amplifier. The design procedure focuses on the noise performance, which is the key requirement for low noise operational amplifiers. Based on the noise level and other specifications such as bandwidth, signal swing, slew rate, and power consumption, the device sizes and the biasing conditions are derived. In order to verify the proposed design procedure, a three-stage operational amplifier has been designed. The device parameters obtained from the proposed design procedure closely agree with the simulated results obtained by using HSPICE.
