Abstract :
In this paper, an 8-bit, 440-MS/s pipelined Analog-to-Digital Converter (ADC) is presented. The ADC utilizes double-sampling in order to relax the operational amplifier (opamp) settling time requirements. Redundant sign digit (RSD) correction compensates offset errors of the comparators. The ADC is designed with a 0.13-μm CMOS process. Simulated effective number of bits (ENOB) of the ADC is 7.09 with the most critical parasitics included and 162-MHz full-scale input, while the current drawn from 1.2V supply is 83mA.
