Patent ID: 8504952

Claim:
A method for designing an electrostatic discharge (ESD) circuit for protection of millimeter wave electrical elements, the method is performed by a computer aided design (CAD) system comprising: determining, by the CAD system, a resistance value of the ESD circuit, wherein the resistance of the ESD circuit is determined based on a class of ESD protection required for the electrical millimeter wave elements; computing a length and a width of a metal line based on the resistance value, wherein the length and the width of the metal line are maximized to meet at most the determined resistance value; computing an inductance value of the metal line; computing, a capacitance value of a capacitor to be connected in parallel to the metal line to resonate the metal line at an operating frequency band of the millimeter wave electrical elements; connecting the metal line to a ground of a multilayer substrate on which the ESD circuit is fabricated, wherein the ESD circuit is fabricated on the multilayer substrate using a fabrication process including at least a deep sub-micron used for a 90 nanometer or below integrated circuit fabrication process; and connecting a capacitor having the computed capacitance value in parallel to the metal line.
