Anomalous gating of asynchronous signals in synchronizers and arbiter circuits may cause significant errors and system failures. Since the probability of logically undefined states at the output of flip-flops increases rapidly with clock rate, the errors were reduced by lower frequencies, at the price of severe time loss, until now. The paper presents a J-K flip-flop in which the duration of an oscillatory or metastable behavior is reduced by a factor of 5 to 15. In this flip-flop the switching of two gates is accelerated by tunnel diodes.
