A different circuit includes a resonant tunneling structure with plural layers, including an outer layer coupled to a further layer made of a material which has a plasma resonance tuned to a selected frequency. Two circuit sections are respectively coupled to the resonant tunneling structure at spaced locations thereon. A bias is applied across the tunneling structure and further layer, and causes the tunneling structure to exhibit a negative resistance.
