Control device for sigma-delta-analog-digital-converter, has storage unit to provide data of digital control signal to time point, and summation unit to sum output signals of quantizer with data to specify data to another time point

摘要

The device has a storage unit (12) to provide data of a digital control signal to a time point, and a modulo-N-operation executing unit to execute a modulo-N-operation. A summation unit (10) sum output signals of a quantizer with the data to specify the data to another time point. A code converter converts the representation of the data of the output signals from a thermometer-code-representation into a binary-code-representation. An independent claim is also included for a method for controlling the dynamic allocation of references to comparators of a quantizer in a sigma-delta-analog-digital-converter.
