Abstract
Circuit topologies that provide extended bandwidth of operation are disclosed. The circuits have two stages that share inductors, in which in-phase current components sum at a summing node and flow together, increasing the magnitude of the current in the inductors. The inductive peaking exhibited by the circuits is increased without using excessively large inductors.
