Abstract
This paper describes an integrated adaptive amplifier for receding electroneurogram (ENG) from tripolar cuff electrodes. The amplifier can automatically compensate for cuff imbalance, thus offering a fully implantable solution to this problem. The circuit was fabricated in 0.8 μm BiCMOS technology with an active area of 0.7 mm . Measured results showed that the ENG amplifier has a cuff imbalance correction range of > ±40%, and a signal-to-interference ratio of about 2/1 (6 dB) even for ±40% imbalance.
