Abstract :
A comparator, fabricated in a 1.5 V/0.12 mum CMOS process, is presented. The commonly separated reset and active-load transistors of typical comparators are combined. In the input part two NMOS transistors are added to reduce power consumption. At a supply voltage of 0.5 V the comparator works at a maximal clock of 600 MHz and consumes 18 muW
