Abstract

The present invention is directed to an integrated filter device for an implantable element. The device includes at least one filter component having N-circuit layers, N being an integer greater than or equal to one. Each of the N-circuit layers includes a first dielectric material having a first conductive material disposed thereon, the first dielectric material being characterized by a relatively low dielectric constant. The first conductive material is characterized by a relatively high electrical conductivity and arranged in a predetermined pattern on a surface of the first dielectric material of each of the N-circuit layers. The first conductive material on each of the N-circuit layers is coupled to the first conductive material disposed on an adjacent layer of the N-circuit layers such that the N-circuit layers form an inductor disposed in parallel with a first capacitance. At least one tuning element is coupled to the at least one filter component and configured to tune the at least one filter component to resonate at a predetermined selected resonance frequency. The at least one tuning element includes a second dielectric material characterized by a relatively high dielectric constant. A dimension of the at least one tuning element and the predetermined selected resonance frequency are a function of a ratio of the high dielectric constant over the low dielectric constant.
