Abstract: PROBLEM TO BE SOLVED: To provide a control device that is used for controlling the dynamic allocation of each reference to each comparator of a quantizer in SD/ADC and implemented with extremely low complexity.
SOLUTION: A control device (8') is used for the dynamic allocation of N references to N comparators of a quantizer in a sigma-delta type analog/digital converter (SD-ADC). This control device (8') generates a digital control signal (9'). Furthermore, the control device (8') includes a storage means (12) for forming a value of the control signal (9') at a time k-1, and an addition means (10) for adding an output signal Y of the quantizer and the stored value of the first control signal (9') at the time k-1.

Abstract: The invention relates to a circuit for low noise, fully differential amplification. A feedback signal (121) is detected in a differential output step of the differential amplification circuit by means of a voltage distributor formed by a first feedback resistance (119) and a second feedback resistance (120). A first output signal (111) is provided at a first output circuit node (117) and a second output signal (112) is provided at a second output circuit node (118). The respective first and second output signals (111) or (112) form a full output signal which corresponds to an input signal formed by a first and a second input signal (101) or (102). A load current (134), an input current (132) and a reference current (132) are established by means of a load current source (128), an input current source (131) and a reference current source (127). A matching transistor (301) is used to adjust an adaptation between the load current source (128), the input current source (131) and the reference current source (127). A feedback signal (121) of the differential amplification circuit is compared with a reference voltage (122) in a reference step, and the load current (134) is mirrored in the differential input step, in a current mirror device.

Abstract: 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.
