Improved Chopper Stabilized Amplifier for Offset and 1/f Noise Cancellation

2006 13th IEEE International Conference on Electronics, Circuits and Systems, 2006
The limits of the conventional chopper stabilization technique for cancelling the 1/f noise are studied theoretically and with simulations. The expected replicas of the 1/f noise at the chopping frequency and its multiples are attenuated by a modified chopping control.

Accurate Airborne Surface Temperature Measurements with Chopper-stabilized Radiometers

Journal of Atmospheric and Oceanic Technology, 1991
Abstract The accuracy of chopper-stabilized radiometers for the meteorological measurement of surface temperatures was investigated during a series of airborne trails, including tests at high altitude using a pressurized aircraft. The significant finding was that these radiometers need to be frequently calibrated during flight to ensure accurate ...

A current-reuse complementary-input chopper-stabilized amplifier for neural recording

2014 IEEE 12th International New Circuits and Systems Conference (NEWCAS), 2014
This paper presents a current-reuse complementary-input (CRCI) telescopic-cascode chopper stabilized amplifier with low-noise low-power operation. The current-reuse complementary-input strategy doubles the amplifier's effective transconductance by full current-reuse between complementary inputs, which significantly improves the noise-power efficiency ...

A time-interleaved chopper-stabilized delta-sigma analog to digital converter

9th International Conference on Electronics, Circuits and Systems, 2003
Although /spl Delta//spl Sigma/ modulators are widely used for low to moderate rate analog-to-digital conversion, the time oversampling requirement has limited their application to higher rate converters. This paper presents a new architecture of time-interleaved /spl Delta//spl Sigma/ ADC using chopper-stabilized techniques in order to eliminate the ...

A Low Noise Operational Amplifier Design Using Chopper Stability

Key Engineering Materials, 2013
Noise has become a significant bottleneck limiting the performance of the op amp, and chopper stabilization technology [1] is commonly used to reduce the noise of the op amp. The chopper stabilization technology can significantly reduce the low-frequency 1/f noise of op amp, then reducing the total low-frequency noise of op amp.

Chopper stabilized laser-Doppler skin blood velocimeter

SPIE Proceedings, 1993
Laser-Doppler velocimetry (LDV) is an established technique for noninvasive monitoring of skin blood flow. The LDV is based on the interference between the photons scattered from the moving red cells and the surrounding stationary tissue. In this work we have developed a new chopper stabilized LDV method.
