Abstract

See full text

A rectification circuit has a first terminal to which an alternating-current voltage is input from an antenna, a second terminal to which a direct-current voltage is input from the antenna, a first rectification element, a second rectification element, and a voltage rectification circuit. The first rectification element is connected between the first terminal and the second terminal, causes a current to flow in a first direction from the first terminal to the second terminal, and cuts off a current in a second direction from the second terminal to the first terminal. The second rectification element is connected between the first terminal and the second terminal, causes a current to flow in the second direction, and cuts off a current in the first direction. The voltage rectification circuit outputs a rectified voltage obtained by rectifying a voltage that is input between the first terminal and the second terminal.
