Abstract:
1. Cross-coupled helical inductor configuration formed in an integrated circuit (IC), the cross-coupled helical inductor configuration comprising: a first helical inductor comprising a first plurality of conductors, wherein the conductors of said first plurality of conductors are disposed in respective layers of the IC and are conductively connected to form a first helical pattern of conductors; a second helical inductor comprising a second plurality of conductors, wherein the conductors of said second plurality of conductors are disposed in respective layers of the IC and are conductively connected to form a second helical pattern of conductors, the first and second helical inductors being positioned in close proximity to one another in the IC; a first coupling conductor that connects at least a first one of said first plurality of conductors to at least a first one of said second plurality of conductors; and a second coupling element that connects at least a second one of said second plurality of conductors to a second coupling conductor to at least a second one of said second plurality of conductors.
