Noise Analysis and Simulation of Chopper Amplifier [PDF]

APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006
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.

Measurement and Analysis of Current Noise in Chopper Amplifiers

IEEE Journal of Solid-State Circuits, 2013
This paper presents a theoretical analysis and measurements of the current noise of several chopper instrumentation amplifiers, which demonstrate that the charge injection and clock feed-through associated with the MOSFETs of the input chopper give rise to significant input current and current noise.
