Flicker Noise Analysis on Chopper Amplifier

2021 19th IEEE International New Circuits and Systems Conference (NEWCAS), 2021
This paper aims to maximize the performance of the chopper amplifier, considering the design trade-off between noise and power consumption. To achieve the goal, we identify and model the various sources of flicker noise in the amplifier and switches using Verilog-AMS language. Then, we build a chopper amplifier circuit and investigate the influences of

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.

Chopper Capacitively Coupled Instrumentation Amplifier Capable of Handling Large Electrode Offset for Biopotential Recordings

IEEE Transactions on Circuits and Systems II: Express Briefs, 2017
This brief presents the design of a low-noise chopper capacitively coupled instrumentation amplifier (CCIA). To accommodate the input with large electrode offset (EOS), the amplifier includes a coarse digital dc-servo loop (DSL) in addition to a fine ...

Analysis of a Chopper Amplifier [PDF]

IETE Journal of Research, 1970
Choppers are often required for obtaining low drift performance of low level d.c. amplifiers. The chopper amplifier basically consists of a modulator, an a.c. amplifier, a synchronous demodulator and a low pass filter. The drift-free performance results from the use of the ‘drift-less’ a.c. amplifier for amplification.The a.c.
