A new high speed, low power and small area CMOS current comparator based on a resistive feedback network is proposed. Simulation results employing 0.35μm CMOS parameters demonstrate 7ns response time and 0.45mW power consumption for 0.1μA input current, which represents a ∼400% improvement in power-delay product over existing current comparators. In this design, the bias current and the input impedance are well controlled parameters, and the inherent autozeroing scheme does not require any offset compensation.
