METASTABILITY COMPENSATION

The disclosure relates to a data processor comprising: a data processing module comprising: an input for receiving an input signal; an output for providing a quantized output signal; a combining unit configured to combine a feedback signal from the output with the input signal; and a quantizer configured to provide the quantized output signal based on the combined signal, wherein the quantized output signal comprises a metastability error, and a correction module configured to: receive the quantized output signal; generate a full-scale digital signal based on the quantized output signal; determine the a metastability error in the full-scale digital quantized output signal; and provide a compensated output signal based on the quantized output signal and the determined metastability error.
