Abstract:
1. A power rectifier for a Radio Frequency Identification tag, comprising: an antenna input node configured to receive wirelessly an alternating signal; and a plurality of serially coupled stages, at least one of the stages coupled to the antenna input node, and including a first Hybrid element and a second Hybrid element, the first Hybrid element including: in which the input terminal of the first device is connected to the output terminal of the first transistor to form a first intermediate node that is not connected to any other components, and the first gate is coupled to the antenna input node, the first device is not biased by the alternating signal; the output terminal of the second device is connected to the input terminal of the second transistor to form a second intermediate node that is not connected to any other components, the second gate is coupled to the antenna input node, and the second device is one of a PNP transistor, an NPN transistor, a Schottky diode, and a diode-connected native NMOS transistor.
