Abstract
An RF-DC power conversion system is designed to ef-
ficiently convert far-field RF energy to DC voltages at very low re-
ceived power and voltages. Passive rectifier circuits are designed in
a 0.25
m CMOS technology using floating gate transistors as rec-
tifying diodes. The 36-stage rectifier can rectify input voltages as
low as 50 mV with a voltage gain of 6.4 and operates with received
power as low as 5.5
W(
22.6 dBm). Optimized for far field, the
circuit operates at a distance of 44 m from a 4 W
