Patent ID: 6927718

Claim:
A circuit arrangement having a circuit which operates continuously in the time domain on the basis of the Σ-Δ principle, comprising: at least one integrating circuit comprising an integration element and a first transfer function associated therewith that is dependent on the integration element; at least one comparison circuit having a clock signal applied thereto, configured to compare an output signal coming from the at least one integrating circuit with a reference signal and deliver a digital output signal that comprises at least one bit in response to the comparison; an apparatus for signal feedback connected to the output of the comparison circuit and to the input of the at least one integrating circuit, wherein the apparatus is configured to use a charge stored on a charge store for the purpose of feedback, the charge store being charged during a first period and being discharged during a second period, the apparatus for signal feedback having a second transfer function associated therewith that is dependent on the charge on the charge store; and an alignment device configured to align the second transfer function of the apparatus for signal feedback with the first transfer function of the integrating circuit.
