Abstract
This work proposes the new CMOS Current Comparator circuit suitable for High Speed and Low 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. Transient response confirms the very high speed operation of the proposed Current Comparator. In addition to the above, proposed current comparator achieves very low power consumption.
