The invention relates to an A/D converter comprising an input and an output, a D/A converting feedback and a pulse width modulating forward path, the D/A converting feedback comprising at least one feed-back path, the feed-back path establishing a D/A conversion based on at least two D/A conversions subject to uncorrelated errors. The invention further relates to a jitter consequence reducing D/A-converter comprising a jitter-robust intermediate signal established on the basis of a digital input signal. The invention further relates to a method for jitter consequence reduction in a pulse width modulated A/D-converter feedback, comprising establishing at least two D/A-conversions subject to uncorrelated errors, and combining, preferably by summing, said at least two D/A-conversions.
An A/D converter comprising
A jitter consequence reducing D/A-converter comprising a jitter-robust intermediate signal established on a basis of a digital input signal, wherein the jitter-robust intermediate signal comprises a number of effective signal levels greater than a number of effective signal levels in the digital input signal.
A pulse width modulated A/D-converter comprising feedback, wherein the feedback comprises a jitter consequence reducing D/A-converter comprising a jitter-robust intermediate signal established on a basis of a digital input signal, wherein the jitter-robust intermediate signal comprises a number of effective signal levels greater than a number of effective signal levels in the digital input signal.
A method for jitter consequence reduction in a feedback of a pulse width modulated A/D-converter, comprising establishing at least two D/A-conversions subject to uncorrelated errors, and combining said at least two D/A-conversions.
