Crosstalk analysis in CMOS integrated circuits

Abstract

The ICs in LSI technology require multilayer connecting-lead systems employing large leads density, diminishing the physical distance between individual leads. The small lead-to-lead separation results increased crosstalk effects inside the integrated circuits. A method was designed to facilitate the forecast of crosstalks in integrated circuits using simple passive LCR circuit models of connecting lines. It appears possible, given a well defined standard interconnecting technology, to forecast the maximum value of crosstalk in a digital system regardless of the physical length of the mutually interfering leads. This presents a major design advantage since the maximum crossialk value can be determined using simple equations without any need to pe form circuit simulations of digital systems including the influence of parasitic couplings. The application of these limit cases can speed up considerably the design of electromagnetically compatible electronic systems.
