Abstract[English]
A high-speed and low-noise ADC is provided. An analog digital converter outputting a digital signal based on an input analog signal is provided, wherein a most significant bit (MSB) of the digital signal is determined based on a comparison between the analog signal and a predetermined threshold voltage, wherein bits other than the MSB of the digital signal are counted by comparing ramp signals having different voltages at a start based on the comparison and reducing a comparison range varying as time elapses, and wherein the threshold voltage and change rates of the ramp signals are variable.[French]
L'invention concerne un CAN à grande vitesse et à faible bruit. L'invention concerne un convertisseur numérique analogique délivrant un signal numérique sur la base d'un signal analogique d'entrée, un bit le plus significatif (MSB) du signal numérique étant déterminé sur la base d'une comparaison entre le signal analogique et une tension de seuil prédéterminée, des bits autres que le MSB du signal numérique étant comptés par comparaison de signaux de rampe ayant différentes tensions à un début sur la base de la comparaison et réduisant une plage de comparaison variant lorsque le temps s'écoule, et la tension de seuil et les taux de changement des signaux de rampe étant variables.
