CMOS amplifier with Chopper Stabilization and Offset Calibration

2020 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2020
A high-precision CMOS amplifier architecture is presented. The proposed architecture features chopper stabilization, as well as means to calibrate its zero offset. The simulation results are confirmed by experimental measurements of silicone devices.

31.4 A Chopper-Stabilized Amplifier with -107dB IMD and 28dB Suppression of Chopper-Induced IMD

2021 IEEE International Solid- State Circuits Conference (ISSCC), 2021
Amplifiers often employ chopping to achieve low offset and low-frequency noise. However, the interaction between the input signal and the chopper clock can cause chopper-induced intermodulation distortion (IMD) [1] –[5]. This is especially problematic for input frequencies (Fin) near even multiples of the chopping frequency (FCH), as the resulting IMD ...

A CMOS Chopper Offset-Stabilized Opamp

IEEE Journal of Solid-State Circuits, 2006
In this paper we introduce an offset-stabilized operational amplifier that uses a chopper amplifier in a low frequency path to cancel the offset of a wide-bandwidth amplifier. A sample-and-hold circuit is used to reduce the chopper ripple, and the low frequency path is also offset-stabilized to further reduce the residual offset. The amplifier has 1muV

Chopper-stabilized sigma-delta modulator

1993 IEEE International Symposium on Circuits and Systems, 2002
A new architecture of the sigma-dela modulators using a chopper-stabilized configuration is described. It is shown that using this new architecture and without any other circuit techniques, a sigma-delta modulator becomes immune from the contamination of the inherent low-frequency noise, such as offset noise, flicker noise, and clock feedthrough noise.

A chopper-stabilized high-pass Delta–Sigma Modulator with reduced chopper charge injection

Microelectronics Journal, 2011
In this paper, a chopper-stabilized high-pass Delta-Sigma Modulator (DSM) is reported with experimental results. A new circuit technique to suppress the residual offset caused by the chopper switch charge injection is proposed. Enabled by an amplifier sharing architecture, the technique diverts the error charge generated by the critical chopper to the ...

Transient processes and stability in an LC chopper

IEEE Transactions on Aerospace and Electronic Systems, 1988
The analysis of the transient and steady-state processes in LC choppers is presented. The method, used previously for the analysis of processes in grid-connected and self-commutated converters, is adjusted for analysis of LC chopper's processes. The difference equations describing these processes, are obtained and solved. The analytical solution of the
