WebComparator, CMOS comparator, Sigma-delta ADC, Low power design, High-speed. Abstract This master thesis describes the design of high-speed latched comparator with 6-bit resolution, full scale voltage of 1.6 V and the sampling frequency of 250 MHz. The comparator is designed in a 0.35 9m CMOS process with a supply voltage of 3.3 V. Web• With an NMOS sampling switch, as V IN approaches V DD-V TH, R ON increases dramatically In smaller technologies, as V DD decreases the swing at V IN is severely limited Sampling switch must be sized for worst case R ON so that the bandwidth is still sufficient 1 ON nox DD IN TH R W
