Abstract:
1. An extended bandwidth active circuit device, comprising: at least two inductors, each inductor having an inductance, a first terminal, and a second terminal, each first terminal thereof in common electrical communication; a plurality of active circuit elements, each of said active circuit elements having a first terminal and a second terminal, at least a first pair of active circuit elements and a second pair of active circuit elements configured to conduct mutually in-phase current components; and two summing nodes, each summing node having an electrical connection to a first terminal of one member of said first pair of active circuit elements and a first terminal of one member of said second pair of active circuit elements, said electrical connection configured so that said in-phase current components sum at said summing nodes, each of said summing nodes in electrical communication with a respective one of said second terminals of said inductors; whereby, when said in-phase current components sum and flow through said two inductors, said extended bandwidth active circuit device provides inductive peaking.
