Abstract
A phase shifter includes an active region, a first and a second set of gates and a set of contacts. The active region extends in a first direction and is located at a first level. The first and second set of gates each extend in a second direction, overlap the active region and are located at a second level. The second set of gates are positioned along opposite edges of the active region, are configured to receive a first voltage, and are part of a first transistor. The first transistor is configured to adjust a first capacitance of the phase shifter responsive to the first voltage. The set of contacts extend in the second direction, are over the active region, are located at a third level, and are positioned between at least the second set of gates.
