提出了一种具有片上高分辨率 A/D 转换器的低功耗 32 通道神经记录系统的设计。包括低噪声全差分前置放大器、增益级和缓冲器的神经前端仅消耗 56 muW。两个以 512 KHz 采样率运行的 13 位扩展计数 A/D 转换器与芯片上的 32 个神经前端集成。实验样机采用0.6μm CMOS工艺设计。采用3.3V供电，芯片总功耗为22mW，整个系统占地3mm×3mm。
A design of low-power 32-channel neural recording system with on-chip high-resolution A/D converters is presented. A neural front-end including low-noise fully differential pre-amplifier, gain stage, and buffer consumes only 56 muW. Two 13-bits extended counting A/D converters running at 512 KHz sampling rate are integrated with 32 neural front-ends on a chip. The experimental prototype was designed in 0.6 mum CMOS process. With a 3.3 V power supply, total power consumption of a chip is 22 mW and the whole system occupies an area of 3 mm times 3 mm.
