Abstract:
1. An apparatus comprising a distributed resonant tunneling section which includes: a plurality of inductive portions coupled in series with each other between first and second nodes, such that a respective further node is present between each adjacent pair of said inductive portions; a plurality of resonant tunneling device portions, each said resonant tunneling device portion being coupled between a third node and a respective said further node; an integrated circuit which includes said first and second nodes at respective spaced first and second locations, and which includes first and second sections that each extend from a region of said first location to a region of said second location, said first section including a plurality of different portions which each include a respective said inductive portion, and said second section including a plurality of different portions which each include a respective said resonant tunneling device portion; wherein said second section includes a plurality of layers which each extend from the region of said first location to the region of said second location, and which each include a plurality of portions that are each part of a respective said resonant tunneling device portion; and wherein said layers of said second section include, in sequence, first, second, third, fourth and fifth layers, said third layer being a lightly doped semiconductor material, said second and fourth layers each being an insulating material, and said first and fifth layers each being a highly doped semiconductor material which is electrically conductive.
