We propose an implantable CMOS micro system for detection of neural spike signals from complex brain neural potentials which achieves the characteristics of ultra low-power and high-precision. The neural recording micro system consists of a low-noise bioamplifier, a neural spike detector based on nonlinear energy operator (NEO) and a precision hysteresis comparator. The DC offset in the bioamplifier is rejected by introducing a new active feedback configuration instead of the large capacitors… CONTINUE READING
