Abstract

The importance of this research lies in the fact that future IC integration will include not only digital and analog circuits, but also power electronic circuits, and the influence of EMI noise induced by the power electronic circuits on digital and analog circuits becomes crucial in overall system design. EMI noise coupled into CMOS logic circuits by a high frequency AC bus carrying square wave has been studied. Parasitics have been extracted using the finite element method incorporated in the parameter extraction software package Ansoft S13D. The influences of the permittivity of PCB materials, the separation between the AC power bus and logic bus and the operation frequencies on EMI noise are especially investigated
