This paper presents a 9-bit 25 kS/s SAR ADC in 0.18 μm CMOS technology for neural signal recording applications. The ADC is powered by a single supply voltage of 1V to comply with other digital processing units on the same chip. The proposed ADC has one common-mode DC input of 0.5V thus offering a f...
