A Low-Noise Chopper Amplifier with Offset and Low-Frequency Noise Compensation DC Servo Loop

The low-frequency and low-amplitude characteristics of neural signals poses challenges to neural signals recording. A low noise amplifier (LNA) plays an important role in the recording front-end. A chopper-stabilized analog front-end amplifier (FEA) for neural signal acquisition is presented in this...
