Abstract
(EN)
Timing signal generation and distribution are combined in operation of a signal path (15) exhibiting endless electromagnetic continuity affording signal phase inversion and having associated regenerative active means (21). Two or more phases of substantially square-wave bipolar signals arise directly in travelling wave transmission-line embodiments compatible with semiconductor fabrication including CMOS. Coordination by attainable frequency synchronism with phase coherence for several such oscillating signal paths has intra-IC inter-IC and printed circuit board impact, as does two-way simultaneous data transfer.
(FR)
La génération et la distribution des signaux de synchronisation se combinent dans la mise en oeuvre d'un chemin de signal (15) à continuité électromagnétique sans fin permettant l'inversion de phase du signal, chemin auquel sont associés des moyens actifs de régénération (21). Deux phases au moins de signaux bipolaires sensiblement en onde carrée surgissent directement dans des réalisations de ligne de transmission à ondes progressives compatibles avec la fabrication de semi-conducteurs, y-compris les CMOS. La coordination au moyen d'un synchronisme de fréquence réalisable avec cohérence de phase pour plusieurs tels chemins de signaux oscillants présente un impact interne au circuit intégré, entre circuits intégrés, et au niveau de la carte à circuits imprimés, comme dans le cas d'un transfert de données bilatéral simultané.
