Abstract
Conventional SPICE-like simulators are not adequate for the noise simulation of the chopper amplifier, which typically has no DC operating point. This paper discusses the noise properties of the chopper amplifier in both time domain and frequency domain and presents a method of simulating chopper amplifier noise behavior with the RF simulator-SpectreRF. The simulation results for a designed circuit are given. A comparison between the simulation and the calculation results shows effectiveness and efficiency of this method in dealing with chopper amplifier noise simulation
