Design of CMOS Current Comparator FVF with VF Level Shifter using for Low Power Applications

A new method is discovered by a flipped voltage follower with voltage follower level shifter (LSFVF) is comparator input stage. The CMOS current comparator design reduces power consumption and improvesspeed of the performance. The conventional current comparator is used for high speed response and low voltage. The comparators are compared in terms of parameters like delay, power dissipation, number of transistors used.The Circuit simulations were performed in CMOS 130nm technology.
