Abstract

This paper presents a low power neural signal amplifier with tunable cut-off frequencies. The presented compact amplifier, which is used for sensing various types of neural signals, reduces the size and the power consumption of the whole circuit. The distinguishing features of this solution are the large time constant, linearity, and small achievable area, which are realized with a configurable series of pseudo resistances. The proof of concept has been manufactured on TSMC 90nm technology.
