Abstract: An amplifier and method of setting the amplifier is presented. The amplifier is set by setting a mean value between voltage values at first and second outputs of the amplifier. The mean value is pulled towards a certain voltage potential. A circuit node is coupled to the first and to the second output. The circuit node is connected, via at least one resistor and a respective switch, to the certain voltage potential assigned to the respective resistor.

Abstract: The converter has two segments of partitioned cell arrangement (14) wit number of converter cells (15a, 17a) and redundant converter cells (15b, 17b). Weighted redundant converter cells are provided in the two segments . The converter cells and the redundant converter cells have same weight within the segments. An online-self calibration unit contains an individual reference cell for calibrating the converter cells (15a, 17a). An independent claim is also included for a method of online-calibration of converter cells of a digital to analog converter.

Abstract: The invention relates to a quantizer ( 1 ) for a sigma delta modulator ( 10 ) having at least one input stage ( 2 ), the quantizer quantizing an input signal ( 21 ) present at its input stage in accordance with at least one threshold signal and outputting it as result value ( 22 ) at a digital result output ( 23 ). Furthermore, the invention relates to a sigma delta modulator having such a quantizer.
