| Summary: | A load circuit for use with a switching mode circuit. The novel load circuit includes a series inductive-capacitive network coupled to an output of the switching mode circuit and a circuit for providing a capacitance coupled to the output of the switching mode circuit. In an illustrative embodiment, the circuit for providing capacitance includes one or more lumped capacitors adapted to compensate for an intrinsic capacitance in the switching mode circuit. The load circuit may also include a shunt inductance coupled to the output of the switching mode circuit. In an illustrative embodiment, the load circuit is adapted to provide a Class-E load to a two-stage Class-E high power amplifier. The amplifier includes a driver stage, a novel Class-E inter-stage matching network (ISMN), and a high power stage using the novel load circuit. |
