NRSD8 - Neural recording and spike detection multichannel integrated circuit designed in 180nm CMOS technology

We present a design and simulation results of an integrated circuit dedicated to recording and detection of a broad range of biomedical signals. The chip is designed in a 180nm CMOS technology and occupies 1.5×1.5 mm
²
. It consists of 8 channels responsible for amplification, filtration, and detection of biomedical signals. Main parameters of the single recording channel such as a voltage gain, frequency band, voltage offset, and a threshold detection, are controlled independently by onchip digital registers. The single recording channel is supplied from ±0.9 V and consumes about 8 μW of power.
