Abstract :
A novel non-quasi-static table-based diode model has been built for applications involving wireless power transmission. This model is technology-independent and is suitable for different diodes. Without complicated curve fitting and de-embedding process, this model is directly generated from S-parameters and DC measurements. A new way to deal with DC characteristic is presented. Excellent fitness is achieved at both AC and DC fields as a result. This large-signal model is used in Agilent ADS software. Simulated and measured efficiency results of a rectenna prove the accuracy of the model.
