|Abstract:||Conventional neural-recording systems face limitations in simultaneously achieving a good NEF and low power consumption [1-4]. This is because the input amplifier current consumption is dictated by an input-referred noise requirement that determines the system sensitivity, while the supply voltage is determined by a DR requirement at the analog recording chain output that limits the maximum achievable resolution of the A-to-D conversion. In this paper, a power-efficient neural-recording architecture using a DR-folding technique is presented to enable low-voltage operation without compromising the DR performance. The proposed architecture can operate with only half of the typically required supply voltage, which results in about 50% power reduction. © 2013 IEEE.|
