Abstract
An electrostatic discharge (ESD) protection circuit is provided for protecting transistors of an integrated circuit (IC) from ESD. The ESD protection circuit includes n transistors with n gates and less than n drains where n is an integer greater than 1. At least m resistors have first ends that communicate with at least one of the transistors of the IC, a blocking capacitor of the IC, an input pad of the IC, and an output pad of the IC, and second ends that connect to corresponding drain terminals of said drains where m is an integer greater than or equal to n/2.
