Abstract
A self-biased cross-coupled differential rectifier is
proposed with enhanced power-conversion efficiency (PCE) over
an extended range of input power. A prototype is designed
for ultrahigh-frequency (UHF) 433-MHz radio-frequency power-
harvesting applications and is implemented using a 0.18-
μ
m
CMOS technology. The proposed rectifier architecture is com-
pared with the conventional cross-coupled rectifier. It demon-
strates an improvement of more than 40% in the rectifier PCE and
an input power range extension of more than 50% relative to the
conventional cross-coupled rectifier. A sensitivity of
−
15.2-dBm
(30-
μ
W) input power for 1-V output voltage and a peak PCE of
65% are achieved for a 50-k
Ω
load.
