Low-noise and Low-power Front-end for True-tripolar ENG Amplifier
Abstract
Electroneurogram acquisition systems are usually based on tripolar cuff electrodes that are known to decrease noise from external sources, such as muscular fibers (EMG) or stimulation artifacts. This paper presents a preamplifier associated with this kind of electrode in a true-tripole configuration. It is designed at the transistor level to lower the number of transistors while still rejecting parasitical signals. This integration at the transistor level reduces the size, power consumption and noise of the preamplifier compared to classical true-tripolar structures.
