Abstract

A receiver circuit including an external terminal, a level shifter, a reset circuit, and an inverting circuit is provided. The external terminal receives the external signal. The level shifter shifts a voltage swing range of the external signal to generate a level shifting signal. The level shifter includes a pull-up unit and a pull-down unit coupled in series. The pull-up unit and the pull-down unit are alternatively switched respectively according to the external signal and the internal signal, and thus a leakage path of the level shifter is cut off for different states of the external signal. The reset circuit couples the external terminal and the level shifter and provides a reset path according to the external signal for assisting the switching of the pull-up unit and the pull-down unit. The inverting circuit couples the level shifter and inverts the level shifting signal to generate the internal signal.
