  • Patent number: 7088214
    Abstract: An on-chip multiple tap transformer balun includes a 1st winding and a 2nd winding having two portions. The 1st winding is on a 1st layer of an integrated circuit and is operably coupled for a single ended signal. The 1st and 2nd portions of the 2nd winding are on a 2nd layer of the integrated circuit. The 1st portion of the 2nd winding includes a 1st node, a 2nd node, and a tap. The 1st node is operably coupled to receive a 1st leg of a 1st differential signal and the 2nd node is coupled to a reference potential. The tap of the 1st portion is operably coupled for a 1st leg of a 2nd differential signal. The 2nd portion of the 2nd winding includes a 1st node, 2nd node, and tap. The 1st node is operably coupled to receive a 2nd leg of the 1st differential signal and the 2nd node is operably coupled to the reference potential. The tap of the 2nd portion is coupled for a 2nd leg of the 2nd differential signal.
