Title (EN) DEVICE FOR PROVIDING A SUPPLY VOLTAGE
(FR) DISPOSITIF PERMETTANT DE FOURNIR UNE TENSION D'ALIMENTATION
Abstract:
(EN) This invention concerns a power supply voltage generator (1) for providing a second supply voltage (VDD2) for an electronic circuitry (60). A voltage converter (50) receives a first supply voltage (VDD1), and converts this into said second supply voltage (VDD2), such that its output voltage (VDD2) fluctuates in a control range between a lower limit (VLOW) and an upper limit (VHIGH). A voltage parameter source circuitry (3) generates a voltage parameter signal (VLOW) which is substantially equal to the minimum supply voltage value (Vmin) of the electronic circuitry (60), and feeds this voltage parameter signal (VLOW) to a parameter input (53) of the converter (50). The voltage parameter source circuitry (3) comprises a VCO (10) incorporated in a PLL. The voltage parameter signal (VLOW) is derived from a control signal (Vcontr) for the VCO (10).
(FR) L'invention concerne un générateur (1) de tension d'alimentation électrique générant une seconde tension d'alimentation (VDD2) pour un circuit électronique (60). Un convertisseur de tension (50) reçoit une première tension d'alimentation (VDD1), et la convertit en une seconde tension d'alimentation (VDD2), de sorte que la tension de sortie (VDD2) fluctue dans une plage de régulation comprise entre une limite inférieure (VLOW) et une limite supérieure (VHIGH). Un circuit source (3) de paramètres de tension génère un signal de paramètre de tension (VLOW) sensiblement égal à la valeur de tension d'alimentation minimum (Vmin) du circuit électronique (60), et fournit ce signal (VLOW) à une entrée de paramètre (53) du convertisseur (50). Le circuit source (3) de paramètres de tension comprend un oscillateur (10) commandé par tension (VCO) incorporé dans une boucle à phase asservie (PLL). Le signal de paramètre de tension (VLOW) est dérivé d'un signal de commande (Vcontr) destiné au VCO (10).
