1. A matching network comprising:
a pair of input terminals;
a pair of output terminals; and
at least two reactive components disposed between the pair of input terminals and the pair of output terminals,
wherein:
one of the reactive components comprises a coupled-inductor, the second reactive component is a capacitor, and the capacitor is at least partially realized using the parasitic capacitances of the environment, and
the coupled-inductor comprises a toroidal or semi-toroidal core with flat wires interleaved without notches, wherein the flat wires are interleaved such that along an inner-surface of the toroidal or semi-toroidal core the flat wires overlap and alternate positions.
