Patent ID: 7026904

Claim:
A filter for use in a communications device, comprising: a first inductor coupled between a filter input and a first node; a first capacitor coupled between the filter input and a first supply voltage; a second capacitor coupled in parallel with the first inductor; a third capacitor coupled between the first node and the first supply voltage; and a second inductor coupled between the first node and a second node, wherein the first inductor is a multiple layer inductor having a plurality of layers, each layer having a first surface and a second surface, and wherein the multiple layer inductor includes: a first conductive pattern on the first surface of a first layer of the plurality of layers; a second conductive pattern on the first surface of a second layer of the plurality of layers; an interconnection coupled to said first and second conductive patterns; and a first conductive side shield pattern and a second conductive side shield pattern disposed on respective perimeters of the first and second layers.
