Abstract :
This paper presents an improved current comparator using flipped voltage follower (FVF) to obtain the single supply voltage. This circuit exhibits short propagation delay and occupies a small chip area. The proposed circuit has been simulated employing PSpice simulator for 0.18 μm CMOS technology and a comparison has been performed with its non FVF counterpart to contrast its effectiveness, simplicity, compactness and low power consumption.
