ABSTRACT:
A transformer comprises a first inductor and a second inductor. The first inductor has one or more trenches and comprises a first conductor defining a signal path along the one or more trenches of the first inductor. The second inductor has one or more trenches and comprises a second conductor defining a signal path along the one or more trenches of the second inductor.
