Résumé
Micro power converters are required for power sensitive, battery-operated devices. Keeping this goal in mind IMTdeveloped a 13-bit RSD cyclic converter. However, inaccuracies (capacitor mis-match, operation amplifier...) resulted in a relative precision behaviour. The implementation of a correction algorithm in a 2μm CMOS technology is presented. It requires 1 mm<sup>2</sup> and simulations show that power consumption is less then 10 μW at 1.25 V. Consequently a fully linear 13-bitA/D converter featuring about 60 m W power consumption at 16 kHz and ± 1.25 V is feasible and will soon be realized as MPW.
