A novel current comparator circuit, made in CMOS technology, for a fast and energy-efficient comparison of small currents. It is difficult to compare very small currents (less than 3·A difference) in a dynamic (i.e., clocked) system, working at high frequency (up to 400 Mhz). These include the following: 1. Speed (400 Mhz and higher)
