摘要：

In this paper, a simple model for the UHF low power rectifier circuit is proposed. Using a novel approach to model the rectifier current waveform, simple analytical equations are derived. The output dc voltage and the efficiency of the rectifier are derived analytically. Simulation results of the rectifier using actual models are very close to those predicted by the proposed model. The derived formulas for the output dc voltage and the efficiency are simple and physically meaningful and can be used to optimize the performance of the rectifier.
