EMI-Receiver Simulation Model with Quasi-Peak Detector

Computer aided design and simulations are an integral part in the development process of integrated circuits. In order to evaluate the electromagnetic compatibility (EMC) of integrated circuits in simulation, simulation models of the EMC measurement setup and the EMC measurement device are needed. In this work, an electromagnetic interference (EMI) receiver simulation model is presented. The EMI-reciever simulation model is intended to analyze electromagnetic emission (EME) of integrated circuits from transient simulations. The model is explained in detail and emulates an CISPR-16 conform test receiver. It is implemented using an STFT algorithm, and evaluates simulation output in CISPR Band-B/C/D with peak, average and quasi-peak detector. A quasi-peak detector model for pulsed disturbances is described, that significantly reduces simulation time compared to traditional implementations. The presented EMI-receiver model is verified with different test setups.
