Abstract
An analog to digital converter comprises coarse (15, 16) and fine (24, 19) quantization. The coarse quantization is of the frequency-current type or frequency-voltage frequency type. The fine quantization measures the discharge period of a residual charge stored in an integration capacitor (3) at the end of the coarse quantization phase. The discharger of this capacitor includes a capacitor (14) for quantifying this discharge.
