A Chopper Stabilized Current-Feedback Instrumentation Amplifier for EEG Acquisition Applications
Abstract
A low-noise, low-power, chopper-stabilized, current-feedback instrumentation amplifier (CFIA) for bio-potential signal acquisition applications is presented. The proposed design includes an ac-coupled chopper-stabilized CFIA to reduce 1/f noise. It also has a switched-capacitor integrator to reduce the input offset and provide a high-pass filter. The proposed amplifier is designed using a Samsung 0.13-μm CMOS process. The CFIA shows an rms input...
