“…The commonly used output power monitoring module only uses the single-chip microcomputer to interconnect with the sensor to read performance data [32]. In this design, based on the trigger extension, the intelligent power rail switching technology is proposed and applied to the system design, further realizing the demand for improving energy efficiency.…”

“…In the last few decades, high conversion e ciency single-band and dual-band recti ers for both low power and high power have been investigated and reported [9][10][11][12][13][14][15][16][17] . Simultaneously, WPT and EH elds are evolved targeting system architectures with multiple frequencies multi-transmitter and receiver.…”

Generally, a conventional voltage doubler circuit possesses a large variation of its input impedance over the bandwidth, which results in limited bandwidth and low RF-dc conversion efficiency. A basic aspect for designing wideband voltage doubler rectifiers is the use of complex matching circuits to achieve decade and octave impedance and RF-dc conversion efficiency bandwidths. Still, the reported techniques till now have been accompanied by a large fluctuation of the RF-dc conversion efficiency over the operating bandwidth. In this paper, we propose a novel rectification circuit with minimal inter-stage matching that consists of a single short-circuit stub and a virtual battery, which contributes negligible losses and overcomes these existing problems. Consequently, the proposed rectifier circuit achieves a diode physical-limit-bandwidth efficient rectification. In other words, the rectification bandwidth, as well as the peak efficiency, are controlled by the length of the stub and the physical limitation of the diodes.
