Abstract

A fast true/complement (T/C) generator, based on a current switch, is described which guarantees an up-level priority at the in-phase and out-of-phase outputs. During switching, the complementary outputs of the T/C generator have a crossover point which is adjusted to be slightly below the up level of the output signal. If the T/C generator is used as an address phase splitter in conjunction with particular decoding concepts, the up-level priority prevents faulty addressing. Faulty addressing is eliminated by avoiding glitches at the output of the phase splitter and by simultaneously having the crossover point at phase splitter in-phase output IP and out-of-phase output OP adequately spaced from the operating threshold of a succeeding decoder.
