Abstract

In this paper, the generation of spectrally pure sinusoidal signals is discussed. The proposed technique is implemented on a DSP and requires a digital-to-analog converter, an analog-to-digital converter and an analog filter. A modified ΔΣ topology is adopted to efficiently estimate and compensate the digital-to-analog converter non-linearities, while desensitizing the system to the non-idealities of the remaining circuital elements. It is shown that the proposed technique can improve the spurious-free dynamic range of the generated signal
