Abstract
(EN)
This flip flop is provided with: an input and an output terminal; a first and a second control signal terminal; a first output unit which includes a bootstrap capacitor and is connected to the first control signal terminal and the output terminal; a second output unit which is connected to the first output unit and the output terminal; a first input unit which is connected to the input terminal and which charges the bootstrap capacitor; a discharge unit which discharges the bootstrap capacitor; a second input unit which is connected to the input terminal and is connected to the second output unit; a re-set unit which is connected to the second control signal terminal and which controls the discharge unit and the second output unit; a first initiation unit which controls the first output unit; a second initiation unit which controls the first input unit; and a third initiation unit which controls the discharge unit and the second output unit. Due to this configuration, it is possible to have a shift register which is capable of completely ON operation regardless of a clock signal.

L'invention concerne une bascule bistable qui comprend: une borne d'entrée et une borne de sortie; une première et une seconde borne de signal de commande; une première unité de sortie, qui comprend un condensateur d'amorce et est connectée à la première borne de signal de commande et à la borne de sortie; une seconde unité de sortie, qui est connectée à la première unité de sortie et à la borne de sortie; une première unité d'entrée, qui est connectée à la borne d'entrée et charge le condensateur d'amorce; une unité de décharge, qui décharge le condensateur d'amorce; une seconde unité d'entrée, qui est connectée à la borne d'entrée ainsi qu'à la seconde unité de sortie; une unité de réinitialisation, qui est connectée à la seconde borne de signal de commande et commande l'unité de décharge et la seconde unité de sortie; une première unité de déclenchement, qui commande la première unité de sortie; une seconde unité de déclenchement, qui commande la première unité d'entrée; et une troisième unité de déclenchement, qui commande l'unité de décharge et la seconde unité de sortie. Cette configuration permet d'obtenir un registre à décalage pouvant fonctionner complètement sous tension, quel que soit le signal d'horloge.
