Abstract

A system (200) for analog-to-digital signal conversion is provided. The system comprises an analog input signal (201), a digital-to-analog converter (202) configured to generate a reference signal (203), and an amplifier (206) configured to amplify an error signal comprising a difference between the analog input signal (201) and the reference signal (203). The system further comprises a level-crossing based sampling circuit (220) comprising a first comparator (214) configured to compare the error signal with respect to a first reference level, and a second comparator (215) configured to compare the error signal with respect to a second reference level, thereby generating event-based reset signals (221) corresponding to a plurality of sampling instances in order to reset the digital-to-analog converter (202) and further to shift the first reference level and the second reference level through the digital-to-analog converter (202). Moreover, the system comprises a trigger circuit (223) configured to generate reset signals (224) asynchronous to the event-based reset signals (221) in order to reset the digital-to-analog converter (202).
