ABSTRACT:
Two input signals, each being at either of two different amplitudes, are coupled to respective Schottky-barrier gates of one transferred electron logic device (TELD) of relatively low transit-time frequency and coupled via a delay means to respective Schottky-barrier gates of another TELD of relatively high transit-time frequency. When the two input signals are at different amplitudes, the TELD connected via the delay means becomes biased to domain formation, thereby causing an output signal having a first value to be produced. When both input signals are at one of the amplitudes, the other TELD becomes biased to domain formation, thereby causing an output signal having a second value to be produced. When both input signals are of the other of the amplitudes, neither TELD is biased to domain formation, thereby causing an output signal having a third value to be produced.
