Power optimization in current mode circuits

Abstract

We propose a method to minimize power dissipation in current-mode CMOS analog and multiple-valued logic (MVL) circuits employing a stack of current comparators. First, we present an approximation model for current in a current comparator circuit. Power reduction is achieved through turning off the redundant comparator circuits using a switch-architecture… (More)
