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.

IEEE Custom Integrated Circuits Conference, 2022
Many sensors exhibit output impedances greater than a few MΩ, and the subsequent instrumentation amplifier (IA) must be carefully designed to meet the requirements of high input impedance $(\mathrm{R}_{\text{in}})$, low noise and low offset.

A 1.9 µW 127 n V/ √Hz Bio Chopper Amplifier Using a Noise-Efficient Common Mode Cancelation Loop
International Conference on Autonomic and Trusted Computing, 2022Electrical neural stimulation (ENS) is widely used for implantable applications to convey information to nervous tissue. However, ENS will generate large common (CM) artifacts at the electrode tissue, leading to saturate the traditional biopotential ...

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.

A chopper dc instrumental amplifier
Measurement Techniques, 1987Because of their low zero drift chopper, dc amplifiers [I, pp. 22-23] are widely used in measuring equipment. The ratio of the maximum cut-off frequency of such an amplifier to its modulation frequency must be carefully chosen since an increase of its carrier frequency magnifies the effect of high-frequency pulse noise on the output voltage [2] in ...
