A New Built-in-Threshold CMOS Comparator

This paper introduces a novel structure for the comparator of analog – to -digital convertor with built- in threshold. Thus the resistor string can be eliminated. The proposed comparator is simulated using HSpice in TSMC 0.18μm CMOS process. The proposed structure reduces the power consumption and occupies less area compared to conventional comparators due to the elimination of the resistor string in analog-to-digital converters.
