Abstract: This disclosure relates to a current-to-digital converter suitable for wide-ranging current sensing applications. In particular, the current-to-digital converter comprises a delta-sigma analogue-to-digital converter which utilizes a successive-approximation-register to control a modulation of the sensed current so that the digital conversion of the modulated sensed current by the delta-sigma analogue-to-digital converter may be done with high precision.
