A Low-Power CMOS Chopper Amplifier for EEG Acquisition Systems
T demand for technologies that help neuroscientists and clinicians to actively observe a large number of neurons in the brain has increased significantly. Currently the biopotential acquisition systems are bulky and not portable that makes it difficult for the on-going diagnostics and causes discomfort to the patient. There is a need to make these systems more compact and to extend their applic...
متن کاملLow Power Low Noise CMOS Chopper Amplifier
AbstractChopping is a proficient way to reduce the low frequency offset and 1/f noise in amplifiers. In this paper, a low power low noise CMOS chopper amplifier is presented. It is composed of a two stage amplifier. The first stage’s high output impedance and the equivalent Miller capacitance of the second stage constitute together a low pass filter, which reduces the power consumption. The cir...
متن کاملA Dynamic Instrumentation Amplifier for Low-Power and Low-Noise Biopotential Acquisition
Abstract: A low-power and low-noise dynamic instrumentation amplifier (IA) for biopotential acquisition is presented. A dynamic IA that can reduce power consumption with a timely piecewise power-gating method, and noise level with an alternating input and chopper stabilization technique is fabricated with a 0.13-μm CMOS. Using the reconfigurable architecture of the IA, various combinations of t...

متن کاملNano Scale Low Power Chopper Amplifier using Cascode and Miller Compensation Nutrilization in 45 nm CMOS
In this paper, reduced power consumption, low-noise CMOS amplifier using chopper technique is designed, chopper-equalized amplifier had been used as a front end of a voltage-to-frequency converter instrument which performs pretty well, and they were meeting just about every specification, but they had a problem with undesired and unpleasant little offset shifts and jumps. Trying to solve this p...
