Abstract
En 中文
A New differential current conveyor based current comparator is presented in this paper. Differential current conveyor II (DCCII) is designed, modified, and exploited as a comparator with reduced propagation delay and power consumption. New DCCII decreases propagation delay and increases comparator accuracy considerably. Simulation results using Hspice and 0.18 mu m CMOS technology with 1.8V supply voltage confirms a less than 0.63 ns propagation delay at +/- 1 mu A input current. Average power dissipation in +/- 1 mu A input current has a value of 300 mu W. (C) 2011 Elsevier GmbH. All rights reserved.
