Tags: Universiti Malaya, Malaysia, Energy & Environment, Infrastructure, Utilities & Communications
This technology introduces a CMOS rectifier for far-field RF energy harvesters, utilizing a novel reverse DC feeding self-body-biasing technique to achieve scalable threshold voltage for NMOS and PMOS transistors. This adaptive efficiency allows the rectifier to operate more effectively under various conditions, improving overall system performance. Simulations show a peak power conversion efficiency of 72.2% at 953 MHz, with self-limiting output voltage protection for short-range operations. The rectifier is suitable for applications in wireless power transfer and wireless sensor networks. It demonstrates high efficiency in RF-DC conversion with reliable voltage regulation.
