ABSTRACT:
An analog-digital converter operating according to the parallel method includes clock-controlled comparators having reference voltages, the reference voltage of a given one of the comparators being closet to a given analog voltage at a sampling instant, a device for feeding in a clock signal, a device for feeding in an analog signal, and a device connected between the comparators and the clock signal and analog signal feeding devices for setting equal propagation times of the clock signal and the analog signal fed to at least the given one of the comparators.
