Abstract:
1. A method of generating a layout for a differential circuit, the method comprising: positioning a pair of inductors using step symmetry, one inductor being on an opposite side of an axis of symmetry from another inductor, each inductor having a first terminal and a second terminal; positioning a plurality of components using mirror symmetry with respect to the axis of symmetry, the plurality of components being in operative relation to the pair of inductors; providing a first interconnect segment connecting the first terminal to a first set of the plurality of components; and providing a second interconnect segment connecting the second terminal to a second set of the plurality of components, wherein the first terminal, second terminal, first interconnect segment, and second interconnect segment of a first inductor of the pair of inductors is placed on a first middle axis of the first inductor, wherein the first terminal, second terminal, first interconnect segment, and second interconnect segment of a second inductor of the pair of inductors is placed on a second middle axis of the second inductor, and wherein the axis of symmetry, the first middle axis, and the second middle axis are parallel to each other.
