Abstract
One embodiment of the invention relates to a dynamically adjustable differential band-pass filter. This band-pass filter includes a first leg that has an input portion and an output portion with a first inductor therebetween. It also includes a second leg in parallel with the first leg, where the second leg has an input portion and an output portion with a second inductor therebetween. The first inductor is symmetrically inter-woven with the second inductor. In some embodiments, the band pass filter is configured to compensate for losses due to the inductors. Other band-pass filters and methods are also disclosed.
