Abstract :
A full differential low-voltage, low-power, and high-speed CMOS current comparator has been designed. The circuit is implemented using 0.5 μm CMOS technology and simulated using HSPICE. The comparison is performed in just one clock cycle with a sampling rate of 600 MHz, and can sense currents down to 0.1 μA (without considering the offset). The amount of offset obtained using Monte Carlo simulation is absolutely less than 0.4 μA for 95% of the cases. Power dissipation is less than 1 mW
