EMI-EMC Analysis of Printed Circuit Board Traces

In this paper, the authors present the Electro-Magnetic Interference (EMI) and Electro-Magnetic Compatibility (EMC) analysis of a Printed Circuit Board (PCB). The width of the differential pair trace of the PCB was varied and the emission values were measured and compared, demonstrating an improvement in radiated emissions when the width of the trace was decreased. The trace width of the PCB was increased from 0.1143mm to 0.8mm, which resulted in improvement of emissions up to 40dB.
