This paper presents the design of highly efficient rectifiers that can operate
at WiFi frequencies (2.45 GHz and 5.8 GHz) and match low input power.
The designed dual-band rectifiers use multi-stage dickson voltage multipliers
(DVM) (from 1 to 6 stages), and the main idea of this paper is to find the
number of stages that offers the best performance and that can be used by
applications that operate within the same constraints (operating frequencies,
input power). The efficiency and the output voltage (Vout) are the
parameters studied to analyze the designed rectifiers. The results showed
that as the number of DVM stages increased, the efficiency curves for both
frequencies shifted to the higher input power range, even when using the
same diode (SMS7630) and the same load (5 KΩ). We concluded that the
rectifier with 1-stage DVM is the most suitable to be used for low input
power at the selected frequencies since it provides an efficiency of 57.734%
at 0 dBm for 2.45 GHz and 36.225% at 1 dBm of input power for 5.8 GHz.
