Abstract

A circuit system of detecting neural signal is present in this paper, including a designed analog chip and digital signal process in FPGA. The analog chip contains weak-signal readout circuit and sigma delta modulator. It is implemented in SMIC 0.18μm 1P6M CMOS process. The digital output of the analog chip is sent to FPGA, where the digital signal process realized the split of neural signal. The measurement results show that this circuit system detects the Spike signal and LFP signal well.
