IP개요 An 8-channel neural recording IC with time-multiplexing to interface with 64 input electrodes arranged in an 8x8 array configuration, with multiplexing switches outside the chip. The analog front-end includes a CCIA structure, with DSL and a manually set dual-positive feedback loop, followed by a PGA. The analog output is converted to digital using a ping-pong SAR ADC. A controller arranges the aggregated data for all 64 input electrodes to be output serially from the chip.
