An EMI receiver model to evaluate electromagnetic emissions by simulation

Electromagnetic Compatibility (EMC) standards generally limit the electromagnetic emission (EME) of products, e.g. assembled in a vehicle. The compliance to EME standards is verified by emission measurements using a defined test setup including electromagnetic interference receivers (EMI Receivers). Integrated circuits undergo extensive simulations before they are actually produced. More and more, the electromagnetic emission are also considered and simulated during the product design phase. Consequently, the behaviors of all components that are required for an EMC test have to be included in the simulation. This paper investigates the modeling of an EMI receiver and presents an implementation with short computation time. The model is verified with various test signals.
