We propose a method involving selective signal gating 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 by turning off the redundant comparator circuits using a switch-architecture. Simulations are carried-out for current-mode flash ADC designs and literal generating circuits for MVL to validate the method.
