Abstract
In this paper, a new high-speed current mode comparator based on inherent current conveyor and positive feedback properties is presented. This novel approach has resulted in major reduction of the response time and hence a wide band application of the circuit. Simulation results using HSPICE and 0.18 μm CMOS technology with 1.8 V supply confirms a propagation delay of less than 0.4 ns in the high frequency range of 700 MHz with 158 μw power dissipation. Under the above conditions, the accuracy of the input current is as low as 50 nA.
