Abstract

An ultrawideband rectifier without an external impedance matching circuit offers many benefits, such as compact circuit size and lower losses. Generally, the rectifier is designed using the conventional voltage doubler circuit, which has varying input impedance for the operating frequency. But, to achieve the wideband rectification, the input impedance of the proposed circuit must be matched with 50 O impedance throughout the desired frequency band. For varying impedance, it is challenging to design the impedance matching network. In [11], the idea of a virtual DC battery is utilized to achieve ultra-wideband rectification without using any external matching at input section. For the further improvement of rectification efficiency, in this work, parallel diode connection is proposed instead of single diode. The proposed design achieved maximum flat conversion efficiency for energy harvesting and wireless power transfer applications.
