Abstract :
In this paper, a comparator used for switching regulator is presented. This design uses a bias stage with the structure of negative feedback to get more stable DC bias voltages. The comparator is formed by 3 stages: input stage, a emitter coupled differential pair; middle stage, a folded cascode amplifier and output stage be consisted by a Active Load Inverter. These simulation result shown in this paper is got by Hspice with a 0.6 um CMOS technologies and 3.6 V power supply.
