An analogue/digital converter comprises rough quantizing means (15, 16) and fine quantizing means (24, 19). The rough quantizing means are of the current/frequency or voltage/frequency conversion type with variable frequency. The fine quantizing means comprise means of measuring the discharge time for a residual charge stored in an integrating capacitor (3) on termination of the rough quantizing phase. The means of discharging this capacitor include a capacitor (14) for quantizing this discharge. …<IMAGE>… |
