Abstract
An on-chip differential inductor includes a 1st interwound winding having a substantially octagonal shape, or rectangular octagonal shape, and a 2nd interwound winding having a substantially octagonal shape, or rectangular octagonal shape, that is interwound with the 1st interwound winding. Both the 1st and 2nd interwound windings are on the same layer of the integrated circuit. Each interwound winding includes two nodes; one of node of each winding is commonly coupled to a reference potential. The other node of each winding is operably coupled to receive a respective leg of a differential signal.
