ASIC with 8-channels stimulator and 4-channels neural recording amplifier

An ASIC with 8-channels stimulator and 4-channels neural recording amplifier ("8ChStim/4ChRec") was developed. The main performances of electrical stimulator are: current range up to 5mA in four scales with 6 bits resolution (2, 5, 20 and 50uA); programmable stimuli waveform; 1 us pulse width resolution; stimulation frequency from 7 to 300Hz and burst capability.

The main characteristics of recording amplifiers are: very low noise [5nV/sqr(Hz)], programmable gain and bandwidth and high CMRR. This ASIC can be used to implement a general purpose neural stimulator and recording device using different electrodes such as cuff, sieve or life.
