An on-chip multiple tap transformer balun includes a 1winding and a 2winding having two portions. The 1winding is on a 1layer of an integrated circuit and is operably coupled for a single ended signal. The 1and 2portions of the 2winding are on a 2layer of the integrated circuit. The 1portion of the 2winding includes a 1node, a 2node, and a tap. The 1node is operably coupled to receive a 1leg of a 1differential signal and the 2node is coupled to a reference potential. The tap of the 1portion is operably coupled for a 1leg of a 2differential signal. The 2portion of the 2winding includes a 1node, 2node, and tap. The 1node is operably coupled to receive a 2leg of the 1differential signal and the 2node is operably coupled to the reference potential. The tap of the 2portion is coupled for a 2leg of the 2differential signal. The 1and 2portions of the 2winding are symmetrical with respect to the 1and 2nodes and with respect to the tap nodes.
