Abstract
An RF-DC power conversion system is designed in a 0.25mum CMOS technology to efficiently convert RF energy to DC voltages. The rectifier has 60% efficiency and can rectify input voltages as low as 50mV by using floating gate transistors as rectifying diodes. For distances of 15 meters, 1 volt DC is measured with 0.3muA load current at 906MHz. The system operates with 5.5muW (-22.6 dBm) received power, corresponding to 42 meters operating distance with a 4W source
