A Chopper Stabilized, Current Feedback, Neural Recording Amplifier
IEEE Solid-State Circuits Letters, 2019 Advanced neural prosthetics requires high density neural recording and stimulation electrodes interfacing with the tissue. For an implantable device, area, power consumption, and noise performance are the key design metrics. Due to the low-frequency nature of the recorded signals, chopping technique is inevitable to satisfy the noise requirement while ...
