Abstract
A phase shifter includes a first transistor and a second transistor. The first transistor includes a first gate terminal configured to receive a first voltage. The first transistor is configured to adjust at least a resistance or a first capacitance of the phase shifter responsive to the first voltage. The second transistor is coupled to the first transistor. The second transistor includes a second gate terminal configured to receive a second voltage. The second transistor is configured to adjust a second capacitance of the phase shifter responsive to the second voltage. The second gate terminal includes a first polysilicon portion and a second polysilicon portion extending in a first direction. The first polysilicon portion and the second polysilicon portion are positioned along opposite edges of an active region of the first transistor and the second transistor.
