Title (EN) VOLTAGE GENERATOR CIRCUITRY
(FR) CIRCUIT GENERATEUR DE TENSION
Abstract: front page image
(EN)Voltage generator circuitry uses a first capacitor (Q1) that is selectively isolated from an output terminal (26) by a first transistor (Q4). The gate of (Q4) is coupled to a circuit terminal (16) which is capacitively coupled via second capacitor (Q5) to the output terminal (20) of a delay gate (28). The first capacitor (Q1) is charged to a potential level near or at that of a power supply (VDD) and then a positive going waveform applied to (Q1) causes it to be charged to a potential level above (VDD). Terminal (16) is charged by the positive going waveform to a value at or near (VDD) and then it is increased in potential after the delay time of the delay gate (28) This enables (biases on) (Q4) and allows the output terminal (26) to assume a potential level greater than that of (VDD).
(FR)Un circuit generateur de tension utilise un premier condensateur (Q1) qui est isole selectivement d"une borne de sortie (26) par un premier transistor (Q4). La porte de (Q4) est accouplee a un terminal de circuit (16) qui est capacitivement accouple via un second condensateur (Q5) a la borne de sortie (20) d"une porte de temporisation (28). Le premier condensateur (Q1) est charge avec un potentiel de niveau voisin ou egal a celui d"une alimentation de puissance (VDD) puis une onde positive appliquee a (Q1) charge ce dernier a un niveau de potentiel superieur a (VDD). Le terminal (16) est charge par l"onde positive a une valeur egale ou voisine a (VDD) puis son potentiel augmente apres la temporisation de la porte de temporisation (28). Ceci polarise (Q4) et permet a la borne de sortie (26) de recevoir un potentiel superieur a celui de (VDD).
