Abstract
A distributed electrostatic discharge (ESD) protection circuit for high frequency integrated circuits. A transmission line from an integrated circuit (IC) pad or package pin couples a plurality of ESD elements. The ESD elements, such as diodes, are distributed along the transmission line and coupled from the transmission line to ground or a power supply. The effective impedance of the transmission line and ESD elements is defined to match the impedance of an external line. Distributed ESD protection circuits provide a high frequency signal path that can be used well into the GHz frequency range and also provide effective ESD protection.
