ABSTRACT:
A multi-function resonant tunneling logic gate is provided in which a resonant tunneling transistor (12) includes a first terminal, a second terminal, and a third terminal. A plurality of signal inputs are coupled to the first terminal of the resonant tunneling transistor (12) through a summer (10). Furthermore, a biasing input is operable to apply a bias to the first terminal of resonant tunneling transistor (12) such that the transfer characteristic of the resonant tunneling transistor (12) can be shifted relative to the signal inputs.
