An integrated transient voltage pulse multiplier (360) is used to increase the voltage to the gates of control switches (310) in a low voltage circuit. The increased conductance of the control switches (310) permits a reduction in gate width, reducing parasitic charge (380) injection and capacitive feedthrough. A low distortion switched capacitor filter (590) utilizes two transient voltage pulse multipliers (400) to increase the voltage of non- overlapping clock signals. The switched capacitor filter (400) is operative at a power supply voltage of less than 1.5 volts.
Cette invention se rapporte à un multiplicateur d'impulsions de tension transitoire intégré (360), qui est utilisé pour augmenter la tension aux portes des commutateurs de commande (310) d'un circuit basse tension. La conductance augmentée des commutateurs de commande (310) permet de réduire la largeur des portes, réduisant ainsi l'injection de charges parasites (380) et la traversée capacitive. Un filtre de condensateur commuté à faible distorsion (590) utilise deux multiplicateurs d'impulsions de tension transitoire (400) pour augmenter la tension de signaux d'horloge sans chevauchement. Ce filtre de condensateur commuté (400) fonctionne à une tension d'alimentation inférieure à 1,5 volts.
