Abstract: A multi-bit sigma/delta converter for converting an analog input signal into a digital output signal comprises a filter device for filtering the analog input signal which is added to a feedback signal to form an intermediate signal. An integrator device for integrating the filtered intermediate signal added to an inner feedback signal forms a quantizer input signal. A quantizer device quantizes the quantizer input signal to form the digital output signal. An inner feedback digital/analog converter is provided for converting the digital output signal directly into the inner feedback signal. A DEM device for performing dynamic element matching on the digital output signal and providing a matched digital signal is provided and a feedback digital/analog converter for converting the matched digital signal into the feedback signal is implemented.
