This article proposes a multi-diode-based wide-input power range rectifier for harvesting ambient radio frequency (RF) energy from 915 MHz ultra-high frequency (UHF). L-match series and parallel topology have been designed to not only boost the received input power but also to produce a highly efficient network to hold a broad input power range. 2862) approach to achieve higher efficiency over a wide input power range. From the measurements, the proposed series L match achieves peak power conversion efficiency of 75% at 4 dBm with 35 dB of wide input power range from  23 dBm to 12 dBm with > 20% respectively whereas the proposed parallel L match achieves peak power conversion efficiency of 79% at 4 dBm with 38 dB of wide input power range from  26 dBm to 12 dBm with > 20% in an area of 1:8 X 2 cm 2 respectively.
