    摘要： Logic circuitry (1) includes a resonant-tunneling transistor ( 1) and a resistor (13) connected in series thereto.
    The resonant-tunneling transistor has a superlattice structure and may be a resonant-tunneling hot electron transistor or a resonant-tunneling bipolar transistor.
    The resonant-tunneling transistor is operable to flow a current, between a collector and an emitter, having one of at least three different current values of a first, a second or a third value in response to a base voltage (V IN ) in one of three different voltage values of a first, second or a third value. The third current value lies between the first and second current values, and the second voltage value lies between the first and third voltage values. The logic circuitry outputs one of at least three states having a high value, a low value, and a value approximately in between the high and low values in response to a signal applied to the logic circuitry the signal having an amplitude of one of the first to third voltage values.
