摘要
We present a 64-channels IC front-end for implantable systems using extracellular neural signals for rehabilitation purposes. Each channel of the ASIC consists of a high-pass filter with subthreshold feedback resistance and a line buffer. Channels are scanned through a time-division multiplexer followed by a variable gain amplifier and an output buffer. Power consumption is 500 mu W per channel with +/- 1.65 V dual supply and an excellent noise performance of 2.9 mu Vrms (100 Hz-10 kHz).
