Simulation on the electromagnetic radiation of PCB

摘要

The article gives the electromagnetic radiation characteristics of the A/D converter. The AID converter is a double integrating type. The PCB layout of the AID converter is made with the software layout plus in OrCAD. Two PCB arrangement prototypes of the A/D converter is studied. For each kind of device arrangement, the electromagnetic radiation characteristics are studied using special software Omega Plus for 4- or 2-layer PCB.
