Abstract
An integrated line inductor and line feed resistor is disclosed. A first coil winding and a second coil winding having a select resistance are magnetically coupled to each other. The first coil winding and second coil winding are each operable to transform electric energy between a Subscriber Line Interface Circuit (SLIC) and a tip and ring (T/R) line.
