Title:
RECTIFYING METHOD AND RECTIFYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/079227
Kind Code:
A1
Abstract:
This rectifying device 100 is provided with: at least one MOSFET (PMOSFET 20) in which a gate terminal 26a, a drain terminal 25a, and a well terminal 23a are connected to each other; an alternating current signal generation source 80 which generates an alternating current signal so that the at least one MOSFET operates in a voltage region including a weak inversion region, and which supplies the alternating current signal to a source terminal 24a of the MOSFET; and a capacitor element C connected to the drain terminal 25a of the MOSFET. The MOSFET, which operates even in the weak inversion region by short-circuiting the gate, the drain, and the well, is used as a rectifying element, thereby configuring a rectifying device in which loss due to rectifying and leakage current are reduced, and which, in energy harvesting technology for collecting very weak energy, has a desirably high efficiency, exhibits a low leakage current, and is compatible with high frequencies.
