- Abstract:
- This paper addresses the generation of spectrally pure sinewaves by combining the feedback structure of a ΣΔ loop with digital cancellation of unwanted spectral components in the output signal. In particular, the non-linearities of the in-loop Digital to Analog Converter (DAC) are compensated by applying a digital pre-distortion to the DAC input, and the feedback architecture is used to enhance the performance of the all digital estimation and cancellation algorithm.
