Abstract
This work proposes the new CMOS Current Comparator circuit suitable for High Speed and Marginal Power applications. Proposed circuit had been simulated in a proprietary 180 nm CMOS process, using Cadence Spectre Simulator and UMC models. Current comparator circuit had impressed with current pulses ranging from Milli-Amperes to Nano-Amperes and its Speed and Power consumption had been simulated and measured. When made a comparison with the earlier reported circuits, our circuit achieves Very High Speed of operation and acceptable power consumption. For Micron range input currents the power consumption of the newly proposed current comparator is very much lower than the other earlier proposed circuits.
