Abstract—This paper presents a RF to DC conversion model for
multi-stage rectifiers in UHF RFID transponders. An equation re-
lating the RF power available from the antenna to the DC output
voltage produced by a multi-stage rectifier is presented. The pro-
posed model includes effects of the nonlinear forward voltage drop
in diodes and impedance matching conditions of the antenna to rec-
tifier interface. Fundamental frequency impedance approximation
is used to
