<p>A digitally controlled phase shifter (200) is disclosed. In an exemplary embodiment, an apparatus includes a first component (206) connected between a first terminal (202) and a node (216), a second component (208) connected between a second terminal (204) and the node (216), an impedance (210) selectively connected between the first and second terminals (202, 204) by a first switch (212), and a second switch (214) connected between the node (216) and a ground. The apparatus (200) is configured to provide a first amount of phase shift when the first and second switches (212, 214) are in an open position, and a second amount of phase shift when the first and second switches (212, 214) are in a closed position.</p> |
