A voltage doubler rectifier RF power harvesting system is provided having at least one power harvesting module with a voltage doubler rectifier that includes a DC voltage input and output, signal input, first and second floating gate transistors that are connected in series between the DC voltage input and output, and a gate control of the floating gate is connected to a drain of the transistor. The voltage double rectifier includes a first capacitor disposed between the input signal and the drain of the first floating gate transistor, and a second capacitor disposed between a ground and the drain of the second floating gate transistor. The system includes an input antenna and a transmitter with a transmitter antenna, where a full-wave peak-to-peak voltage of an incoming RF signal is rectified. The system also includes a powered device connected to the DC voltage output to utilize the rectified signal.
A voltage doubler rectifier RF power harvesting system comprising:
The RF power harvesting system of claim 22 wherein said antenna inner loop comprises a perimeter to match said input impedance of said rectifier.
The RF power harvesting system of claim 23 wherein said antenna matching outer loops are disposed to divide said antenna into two identical parts as a virtual ground, wherein a fully differential signal is provided at said antenna ports.
