CPC H03M 1/1014 (2013.01) | 20 Claims |
1. A system for analog-to-digital signal conversion comprising:
an analog input signal;
a digital-to-analog converter configured to generate a reference signal;
an amplifier configured to amplify an error signal comprising a difference between the analog input signal and the reference signal;
a level-crossing based sampling circuit comprising a first comparator configured to compare the error signal with respect to a first reference level, and a second comparator configured to compare the error signal with respect to a second reference level, thereby generating event-based reset signals corresponding to a plurality of sampling instances in order to reset the digital-to-analog converter and further to shift the first reference level and the second reference level through the digital-to-analog converter; and
a trigger circuit configured to generate reset signals asynchronous to the event-based reset signals in order to reset the digital-to-analog converter.
