Abstract
In one example embodiment, a programmable filter is provided, including a plurality of variable-inductance networks and a plurality of variable-capacitance networks. The programmable filter may be implemented in a classical filter topology, with variable-capacitance networks replacing discrete capacitors and variable-inductance networks replacing discrete inductors. An example variable-inductance network comprises a primary inductor with an intermediate tap, and secondary inductor connected at the intermediate tap, with switches for selecting an inductance.
