Abstract:
A method of manufacturing an interconnect system for conveying a signal between a communication circuit implemented within an integrated circuit and an external node outside the integrated circuit, the method comprising the steps of:a. forming an electrostatic discharge (ESD) protection device comprising capacitive impedance within the integrated circuit; b. producing a first conductive path comprising inductive impedance extending from the ESD protection device to the external node; c. providing a second conductive path comprising inductive impedance extending from the communication circuit to the external node; d. selecting a characteristic of a frequency response of the interconnect system from the communication device to the external node; e. evaluating a function of the impedances of the first and second conductive paths, the ESD protection device, and the communication circuit to calculate a magnitude of a capacitance at the external node which will substantially optimize the frequency response characteristic selected at step d; and f. adjusting the capacitance at the external node to approximate the magnitude calculated at step e.
