Abstract

A device is provided herein. The device includes a signal input, an operational amplifier (op-amp) comprising a non-inverting op-amp input, an inverting op-amp input, and an op-amp output, a summer coupled to the op-amp output, a second summer input coupled to the signal input, and a summer output, and a low-pass filter comprising a low-pass filter input coupled to the summer output and a low-pass filter output coupled to the inverting op-amp input. The device processes electrophysiology signals by combining feedforward and feedback paths to achieve DC offset and low-frequency interference rejection while maintaining high input impedance and signal amplification.
