Claim 13:
14. A method, comprising:
providing a plurality of unit cells;
for at least one of the unit cells:
providing a first inductor having a first node coupled to a center conductor and a second node coupled to ground;
providing a first capacitor having a first node coupled to the center conductor and a second node coupled to ground;
providing a second inductor having a first node coupled to the center conductor; and
providing 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;

creating a bandpass parametric amplifier by using the plurality of unit cells as part of a ladder circuit structure; and
for every multiple number of the unit cells, including a resonant structure.
