AB - A chopper-stabilized current-feedback instrumentation amplifier (CFIA) for EEG acquisition applications is presented. The proposed design includes an AC-coupled CFIA and a switched-capacitor (SC) integrator. By using appropriate chopper modulation technique in both input and output stages of the CFIA, 1/f noise is reduced. An input-referred noise power spectral density (PSD) of 63 nV/√Hz is obtained. The SC integrator was employed to control the low cutoff frequency of the CFIA by adjusting the sampling frequency of the SC integrator. Simulation results show that the proposed amplifier provides a common mode rejection ratio (CMRR) of 114 dB and a tunable gain up to 57 dB. The low cutoff frequency is determined within a range from mHz to a few Hz depending on the switching frequency of the SC integrator and the high cutoff frequency is approximately 600 Hz. The total power dissipation of the CFIA is 1.9 μW.
