A CMOS RF-DC Converter in the GSM Band for RF Energy Harvesting Applications
In this work an all pMOS RF-DC power harvester optimized RF energy harvesting applications is presented. The proposed work is optimised for enhanced sensitivity with an L-match network for GSM band driving the cross coupled pMOS based rectifier, where these transistors operate in the weak inversion region. The rectifier performance is tested using simulation in 180nm CMOS technology for varying received power levels. The rectifier achieves an power conversion efficiency (PCE) of 43.15% and voltage conversion efficiency of 68.5% across load $10k\Omega$.
