Abstract :
In the implementation of high-performance CMOS over-sampling A/D converters, high-speed comparators are indispensable. This paper discusses the design and analysis of a low-power regenerative latched CMOS comparator, based on an analytical approach which gives a deeper insight into the associated trade-offs. Calculation details and simulation results for a 20 MHz clocked comparator in a 0.5μm technology are presented.
