Implementation of High Performance Comparator in 90nm Technology.

In this paper a CMOS Differential current sensing comparator along with the Buffer stage has been introduced. In this paper comparator is implemented in a standard TSMC 90nm CMOS technology using Mentor Graphics Tool The simulation is carried out in 90nm technology. The supply voltage for this comparator is ± 0.9v. This paper firstly elaborate about basic introduction of Comparator. Next section elaborate Different Current Sensing Comparator and Buffer Stage. Next section elaborate the design of comparator . Last section consist simulation results.
