Abstract

This paper presents the first fully integrated and pitiless wireless 0.5 V-power supply for RFID applications in 130 nm CMOS. It consists of an on-chip integrated dipole-antenna, a rectifier and storage capacitor. The system can generate 0.5 V from 36.4dBm E1RP at a distance of 0.5 m, the operating frequency being 10.35 GHz plusmn 1%. The integrated antenna is a dipole with a reflector underneath, to shield it from the lossy substrate. The rectifier uses a 20-stage voltage-doubler topology to rectify the incoming power. The die area is only 300 mum times 1500 mum.
