1. An integrated circuit based transformer, comprising:
a primary winding located in a winding layer, the primary winding having two primary terminals at a first side of the transformer; a secondary winding located in a winding layer, the secondary winding having two secondary terminals at a second side of the transformer, the first and second sides located at different sides of the transformer; a reference bar located in a reference bar layer, the reference bar having a primary reference bar terminal at the first side of the transformer, and having a secondary reference bar terminal at the second side of the transformer, wherein the reference bar is configured to provide a direct electrical connection between the first reference bar terminal and the second reference bar terminal, wherein the reference bar is configured to provide a common connection to ground for the primary and second windings, wherein the reference bar is located entirely along a central mirror symmetric axis of the transformer, and wherein each of the primary and secondary windings covers less than one circle; and a tap line located in a tap line layer having a tap line terminal located at a side of the transformer, the tap line providing a connection between the tap line terminal and the primary or secondary winding partway along the winding, wherein the tap line has a longitudinal axis positioned substantially along the longitudinal axis of the reference bar, wherein the tap line comprises a primary tap line and a secondary tap line, and wherein the tap line is positioned such that at least a portion of the longitudinal axis of the tap line is skewed from the longitudinal axis of the reference bar by a tap line angle such that the primary tap line is connected to the middle of the primary winding by a primary tap line via, and the secondary tap line is connected to the middle of the secondary winding by a secondary tap line via. |
