Abstract
A method of analog-to-digital conversion over n bits of an analog signal, including the steps of: comparing the amplitude of the analog signal with a threshold representing the amplitude of the full-scale analog signal divided by 2, where k is an integer smaller than n; performing an analog-to-digital conversion of the analog signal over n−k bits to obtain the n−k most significant bits of a binary word over n bits if the result of the comparison step indicates that the amplitude of the input signal is greater than the threshold, and the n−k least significant bits of this binary word otherwise. An analog-to-digital converter and its application to image sensors.
