Abstract: An apparatus for providing oscillator signals includes an oscillator circuit configured to generate a first oscillator signal with a first oscillator signal frequency for a frequency conversion of a first signal to be converted and to generate a second oscillator signal with a second oscillator signal frequency for a frequency conversion of a second signal to be converted. The oscillator circuit is configured to enable the generation of the first oscillator signal with the first oscillator signal frequency and the second oscillator signal with the second oscillator signal frequency based on at least two different possible oscillator circuit configurations. The control circuit is configured to select, based on the first oscillator signal frequency and the second oscillator signal frequency, one of the possible oscillator circuit configurations of the oscillator circuit for generating the first oscillator signal and the second oscillator signal.

Abstract: A receiver is provided with a digital signal processing circuit to process a receive signal. In addition, the receiver includes an interference detector to detect an interference scenario affecting reception of the signal by the receiver. Depending on the interference scenario detected by the interference detector, the digital signal processing circuit is adapted.

Abstract: 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.
