Abstract: The arrangement has a commutator (1) for oversampling the received signal (S) so that several sample values of a bit cell transmitted with the signal are distributed successively to several output ports and output as intermediate signals, two stages (5,6) for combining first and second groups of intermediate signals to form data and clock recovery signals and a phase regulator (7,8) for setting sampling phases for oversampling the received signal.

Abstract: A folding stage of the convertor has means for sensitizing, inhibiting and enabling signal paths through the convertor such that in a first operating condition, first and second inputs to the stage are switched through to corresponding inputs of a differential amplifier (3) of the respective stage. In a second operating condition a low auxiliary potential is applied to the first input and a high auxiliary potential is applied to the second input. In a third condition a high auxiliary potential is applied to the first input and a low auxiliary potential is applied to the second input. In a fourth condition both inputs are set to a potential between the high and low potentials. Means (13) are also provided to set the amplifier outputs to the same potential in dependence on signals on a control bus (18). Means are also provided feed a signal from a comparator or differential amplifier via an interrogation bus (19) to a control unit (20). Independent claims also cover a self calibration method.

Abstract: Compensation circuit elements can be either activated or deactivated and are connected to an operational amplifier. The amplifier has a set frequency response and the compensation elements correct the given response of the amplifier. A regulator configures the compensation circuit elements to a given specification. An independent claim is included for: (1) a method for one of attenuating and eliminating undesired properties of an operational amplifier
