    摘要: In accordance with an embodiment, a method for operating a signal converter includes converting an analog input signal to a digital output signal, comprising by comparing the analog input signal to an analog comparison signal, and detecting whether the analog input signal exceeds a predetermined maximum or minimum threshold by comparing the analog input signal to an analog threshold signal. The analog comparison signal and the analog threshold signal are generated by a same digital-to-analog converter.

    摘要: A method and a corresponding device reduce the convergence time of a correlation algorithm that uses random signals injected into an analog-to-digital converter (ADC) as input to the algorithm. The method and device involve, at a processor of a pipelined ADC, injecting a random signal into each of a plurality of stages in the pipeline and obtaining digital values generated in response to the random signals. Noise components of residue signals in the plurality of stages are calculated as a function of the digital values and values of the random signals. The noise components correspond to the random signals.

    摘要: A monolithic integrable R-2R resistor network comprises a number of series resistors connected to a terminal resistor; and a plurality of 2R resistor units each capable of being switched by two electronic switches either to ground or to another reference point, a different plurality of 2R resistor units being coupled to the nodes between each of the series resistors, to the node between the terminal resistor and the last resistor of the series resistors and to the node ahead of the first resistor of the series resistors. To compensate for the effects of the variations of the switch resistances caused during manufacture by process parameter fluctuations upon the accuracy of a D/A converter, a switch structure is inserted at each of the nodes which, with respect to the two electronic switches, is of the same kind, and which is permanently in an electrically conducting state. Preferably, there are used insulated-gate field-effect transistors and insulated-gate field-effect transistor structures, the identical electrodes of which, for example, the source electrodes, are directly connected to each of the nodes.
