A filter arrangement comprises a switching element coupled to a filter input, wherein the switching element is controllable by a reference clock signal. The filter arrangement further comprises an input storage element, an output storage element, and a first and a second auxiliary storage element. The first and the second auxiliary storage element can each be connected in parallel to the input storage element or to the output storage element depending on a switching signal. The output storage element is coupled to a filter output. The filter arrangement can be used as a loop filter in an analog-to-digital converter, wherein the output signal of the filter arrangement is quantized to provide an output word. Respective feedback signals can be generated from the output word and be provided to the storage elements.

A device may include an oscillator circuit, a control circuit, a frequency detector circuit, and a processor circuit. The oscillator circuit may include a frequency control input to output an oscillator signal. The frequency of the oscillator signal depends on an input signal applied to the frequency control input. The control circuit is configured to apply a first input signal value, a second input signal value, and a third input signal value to the frequency control input. The frequency detector circuit is configured to detect the first frequency value of the oscillator signal when the first input signal value is applied to the frequency control input, a second frequency value of the oscillator signal when the second input signal value is applied to the frequency control input, and a third frequency value of the oscillator signal when the third input signal value is applied to the frequency control input.

A sigma-delta modulator is supplied with a data word and includes a first and at least one further modulation stage, each having at least two adders. The adders in the first modulation stage process a low-significance component and a delayed more significant component of the data word and provide a result word and a carry at their respective outputs. The adders in the at least one further modulation stage process a low-significance component and a more significant component of the result word and provide a further result word and a carry at their respective outputs. The low-significance component and the more significant component of the result word are provided to the further modulation stages with an unvarying delay. A bit stream is derived from a carry from final instances of the at least two adders in the first modulation stage and in the further modulation stage respectively.

A phase locked loop has a controlled oscillator for outputting an oscillator signal depending on a control signal. A comparator generates a comparison result from a comparison between a reference frequency signal and a feedback signal derived from the oscillator signal. The phase locked loop also has a filter block for filtering the comparison result and for deriving the control signal from the comparison result, where the filter block has a loop filter and a rejection filter for the frequency-selective attenuation of at least one first interference frequency in the comparison result.
