Abstract:
An apparatus for calibrating an analog-to-digital converter is provided. The apparatus includes a reference input generation circuit configured to subsequently generate two reference inputs for calibrating the analog-to-digital converter. The two reference inputs both represent ramp waveforms, wherein the ramp waveforms represented by the two reference inputs are different from each other. Further, the apparatus includes a coupling circuit configured to controllably couple an input node of the analog-to-digital converter to either the reference input generation circuit or to a signal node capable of providing an analog input for digitization.
