摘要
A rectifying circuit includes, in part, first and second NMOS transistors, an impedance matching network, and an RF block circuit. The source and gate terminals of the first NMOS transistor respectively receive the ground potential and a biasing voltage. The second NMOS transistor has a gate terminal coupled to the drain terminal of the first NMOS transistor, a drain terminal coupled to the gate terminal of the first NMOS transistor, and a source terminal receiving the ground potential. The impedance matching network is disposed between the antenna and the drain terminals of the first and second NMOS transistors. The RF block circuit is coupled between the drain terminals of the first and second NMOS transistors and the output terminal of the rectifying circuit. The RF block circuit is adapted to prevent the RF signal from flowing into the output terminal of the rectifying circuit.
