| 摘要 |
An exclusive-OR circuit includes a first pair of field effect transistors (FETs), series coupled to a transferred electron logic device (TELD) and a second pair of FETs, arranged as an inhibit circuit. The second pair of FETs is either coupled in series with the first pair of FETs and TELD or in a parallel-serial relationship therewith in accordance with different embodiments of the invention. When a signal of a given polarity and a signal indicative of that signal are applied respectively to only one gate of each pair of FETs, the TELD produces an output signal. When a signal of a given polarity and a signal indicative of that signal are applied respectively to both gates of each pair of FETs, the second pair of FETs inhibits the TELD from producing an output signal.
