This paper proposes a dual-mode nested RF rectifier for ambient wireless powering. The proposed architecture utilizes a dual-mode nested feedback circuit to enhance the conductivity of the rectifier at low-power while reducing the reverse leakage current at high-power by generating supply voltages at the gates of the PMOS rectifying transistors. The proposed rectifier is fabricated in 65 nm CMOS technology and occupies an area of 6480 µm 2. The measurement results show a peak power conversion efficiency of 86%, 10.1 dB dynamic range, and-19.2 dBm 1-V sensitivity when operating with a 100 kΩ load at the industrial, scientific and medical band 433 MHz. Moreover, the enhanced low-power performance is achieved by reducing the effective threshold voltage of the rectifier by about 37%, compared to a lowthreshold transistor in 65 nm technology. This reduction in the threshold voltage allows the rectifier to operate with efficiency exceeding 10% for input power ≥-40 dBm.
