Abstract:
1. A method comprising: forming a first coil, a second coil and a third coil in a first metal layer above a semiconductor substrate, the first coil adjacent a first portion of the second coil, the third coil adjacent a second portion of the second coil, wherein one of the first and third coils has a connection to the second coil in the first metal layer; connecting the second coil to the other of the first and third coils by forming at least one conductive line in a second metal layer other than the first metal layer, forming a first capacitor having a first electrode connected to a first node, the first node being conductively coupled between the first and second coils; and forming a second capacitor having a second electrode connected to a second node, the second node being conductively coupled between the second and third coils.
