On-chip multiple tap transformer and inductor

An on-chip multiple tap transformed balun includes a 1 winding and a 2 winding having two portions. The 1 winding is on a 1 layer of an integrated circuit and is operably coupled for a single ended signal. The 1 and 2 portions of the 2 winding are on a 2 layer of the integrated circuit. The 1 portio...

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