Abstract
A comparator-based switched-capacitor circuit (CBSC) technique is presented for the design of analog and mixed-signal circuits in scaled CMOS technologies. The technique involves replacing the operational amplifier in a standard switched-capacitor circuit with a comparator and a current source. During charge transfer, the comparator detects the virtual ground condition in place of the opamp which normally forces the virtual ground condition. A prototype 1.5-bit/stage 10-bit 7.9-MS/s pipeline ADC was designed using the comparator-based switched-capacitor technique. The prototype ADC was implemented in 0.18-mum CMOS. It achieves an ENOB of 8.6 bits for a 3.8-MHz input signal and dissipates 2.5 mWKeywords
