Abstract
The invention provides an analog-to-digital converter (ADC) of the single ramp type, comprising a ramp generator (), a clock (), a digital counter () timed by the clock (), and at least one channel () for data processing, the or each channel comprising a comparator () having an input connected to the ramp generator () and the output of which causes for each conversion cycle the storage of the current counter value as a coarse conversion data. According to the present invention, the or each channel () further comprises a delay-chain time interpolator () responsive to the output of the comparator and to the clock (), for interpolating time within a clock period from the triggering time of the comparator, said interpolator delivering a time-interpolation output signal as a fine conversion data which is combined to the coarse conversion data for each conversion cycle. Application to an increased resolution without excess power consumption or increased conversion period.
