    Abstract: Provided is a low-power radio frequency (RF) direct current (DC) rectifier. The low-power RF DC rectifier includes a rectification circuit with first and second to n-th rectification units sequentially rectifying an RF signal input through a first input terminal and a second input terminal. The first rectification unit is disposed between the first and second input terminals and a first output terminal of the first rectification unit. The second rectification unit is disposed between the first rectification unit and a second output terminal of the second rectification unit, is biased by the first rectification unit. The n-th rectification unit is disposed between an immediately previous rectification unit and a rectification output terminal of the rectification circuit, is biased by a rectified voltage output from an immediately preceding rectification unit, and outputs the rectified RF signal through the rectification output terminal.
