  • Cross-coupled inductor pair formed in an integrated circuit
    Patent number: 7782166
    Abstract: Cross-coupled first and second helical inductors formed in an IC. The cross-coupled first and second helical inductors comprise a first helical conductor having a first portion and a second portion, and a second helical conductor having a first portion and a second portion. The second helical conductor is in close proximity to the first helical conductor. The first helical inductor is formed by the first portion of the first helical conductor and the second portion of the second helical conductor. The second helical inductor is formed by the second portion of the first helical conductor and the first portion of the second helical conductor.
