Claim 0:
1. A bandpass parametric amplifier circuit, comprising:
a plurality of unit cells, at least one of the unit cells comprising:
a first inductor having a first node coupled to a center conductor and a second node coupled to ground;
a first capacitor having a first node coupled to the center conductor and a second node coupled to ground;
a second inductor having a first node coupled to the center conductor;
a second capacitor having a first node coupled to a second node of the second inductor, wherein the second capacitor and the second inductor are in series with the center conductor, wherein:
the plurality of unit cells is part of a ladder circuit structure that creates the bandpass parametric amplifier circuit; and
every multiple number of the unit cells further includes a resonant structure.
