Abstract
A multiple-input comparator is disclosed. The multiple-input comparator includes a pair of differential transistors connected by a resister. The gate terminals of the transistor pair serve as the input terminals of the comparator for receiving external voltage for comparison. The terminal of the resistor serves as the current input terminal and is either connected to a current source or a current sink. A power inverter utilizing the multiple-input comparator is also disclosed.
