Abstract
A system-on-chip (SoC) neural recording interface
with 64 channels, 64 16-tap programmable mixed-signal FIR
filters and a fully integrated 915 MHz OOK/FSK PLL-based
wireless transmitter is present ed. Each recording channel has a
fully differential ampli fier with 54 dB gain and utilizes a tunable
low-distortion subthreshold MOS-resistor to reject DC offsets
with an input-referred noise of 6.5 µV and a CMRR of 75 dB.
Each channel contains a modi fied 8-bit SAR ADC with an ENOB
of 7.8-bits and can p
