This paper presents an ultra low-power SAR ADC in 0.18 μm CMOS technology for epileptic seizure detection applications. The ADC is powered by a single supply voltage of both analog and digital circuits to avoid using the level-shifters. A latched comparator is used to quickly generate the comparison...
