Abstract
An analog-to-digital converter for converting an input signal includes a sigma-delta modulator for receiving an analog modulator input signal and for providing a digital modulator output signal and an interference cancellation loop. The interference cancellation loop includes a digital filter, a digital-to-analog converter, and a signal combiner. The digital filter is configured to amplify the sigma-delta output signal in a frequency band, attenuate the sigma-delta output signal outside the frequency band and a transition band surrounding the frequency band, and provide a filtered digital feedback signal. The digital-to-analog converter is configured to convert the filtered digital signal to a cancellation signal. The signal combiner is configured to combine the input signal with the cancellation signal resulting in the modulator input signal, in order to at least partially cancel interference signal portions within the input signal.
