General Solution of a Rectifier Using an Inductive Matching Network

IEEE Microwave and Wireless Components Letters, vol. 30, pp. 1173–1176

Abstract

A rectifier with an inductive matching network can reach good efficiency within a very compact size, and hence, became popular recently. In this letter, a general design solution for the inductive matching network is provided. A criterion for using the inductive matching technique is derived to evaluate the suitability of a specific diode for this operation mode. According to the analysis, adding an extra compensation capacitor in parallel to the diode can extend the applicability of a specific diode. A compact design example is thus implemented based on the proposed methodology. The occupied area is less than 0.35 cm2. Measured peak efficiency (η) of 77.7% is obtained for an input power (Pin) of 12 dBm.
