This paper presents a hybrid single-feed CMOS rectifier for RF energy harvesting at 2.4 GHz. The proposed system achieves high power conversion efficiency across a wide input power range by reconfiguring the power paths. The architecture incorporates 3-stage reconfigurable hybrid rectifiers and each stage as regular V_th MOS rectifier for high input power and low V_th MOS rectifier for low input power. Both the rectifiers are connected in a cross-coupled manner which results in small ON-resistance and low reverse leakage current during forward and reverse biased conditions, respectively. The system designed in UMC 0.18 μm CMOS technology for Wi-Fi frequency (2.4 GHz). The post layout simulation results shows an efficiency >30% for input power levels ranging from -24 dBm to -10 dBm while driving a load of 40 KΩ.
