EMI REDUCTION IN POWER MODULES THROUGH THE USE OF INTEGRATED CAPACITORS ON THE SUBSTRATE LEVEL
摘要
A high frequency, low impedance network is integrated into the substrate level of a power module for the reduction of electromagnetic interference ("EMI"). In one embodiment, capacitance is electrically connected to at least one of the positive conducting layer in a substrate or the negative conducting layer in a substrate and a ground. Integrating a capacitive network of low stray inductance in a substrate of a power module allows relatively small, inexpensive capacitors to be used.
