Abstract: The present description concerns a method of controlling an analog-to-digital converter, wherein most significant bits are determined by successive approximations implementing a first digital-to-analog converter and a second digital-to-analog converter. Further, least significant bits are determined by a time-to-digital conversion by applying a first ramp to the output of the first converter with a third digital-to-analog converter and by applying a second ramp to the output of the second converter with a fourth digital-to-analog converter. The variation direction of the first and second ramps is determined by the comparison of the outputs of the first and second converters at the end of the successive approximations.
