DELTA-SIGMA MODULATOR WITH FEEDBACK SIGNAL MODIFICATION |
摘要 |
A delta-sigma modulator (1) for converting a delta-sigma modulator input signal into a sequence of delta-sigma modulator output values comprising an actual delta-sigma modulator output value and at least one preceding delta-sigma modulator output value preceding the actual delta-sigma modulator output value is presented. At least one feedback signal modifier for modifying a at least one first feedback signal in dependence of the actual delta-sigma modulator output value and the at least one preceding delta-sigma modulator output value is provided. By means of the at least one first feedback signal modifier the signal quality of a subsequent final stage (7) can be improved.
