In one embodiment, the sigma-delta converter includes two series-connected converter stages which are each supplied with a feedback signal, a comparator stage which is connected downstream of the second converter stage, which is supplied with the output signal from the second converter stage and which provides an at least two-value comparator signal, and at least one output stage which has at least one digital integrator and which produces a multibit signal as output signal. The sigma-delta converter also has a first feedback look, which is supplied with the output signal and which has a multibit digital-analog converter which is supplied with the output signal and which converts this output signal into a first feedback signal with an amplitude that is dependent on the output signal, and a second feedback loop, which is supplied with the comparator signal, having a digital-analog converter which converts a signal that is dependent on the comparator signal into the second feedback signal.

Abstract: A receiver circuit for receiving an analog signal comprises a mixer device, a first integrator device coupled to the mixer device, a second integrator device following the first integrator device, a quantizer device, and first and second feedback digital/analog converters. The mixer device mixes the analog signal with a local-oscillator frequency and outputs a mixer current signal. The first integrator device generates a first intermediate signal by integrating the mixer current signal summed with a first feedback current signal, the second integrator device generates a quantizer input signal by integrating the first intermediate signal summed with a second feedback current signal, and the quantizer device generates a digital output signal by quantizing the quantizer input signal. The first feedback digital/analog converter converts the digital output signal into the first feedback current signal and the second feedback digital/analog converter converts the digital output signal into the second feedback current signal.

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.
