Abstract

The aim of this research was to find an optimal front-end for a transmitter by focusing on the circuit implementations of the DDS, but the research also includes the interface to baseband circuitry and system level design aspects of digital communication systems. The theoretical analysis gives an overview of the functioning of DDS, especially with respect to noise and spurs. Although most of this material is already present in the literature, the author extends the analysis at several places:
  • The quantization errors in the CORDIC algorithm are determined for a uniform distribution, independent of the signal. Previous analyses made the pessimistic assumption that the error obtains its maximum value at each quantization step.

  • The worst-case carrier-to-spur ratio bounds resulting from phase truncation are derived.

  • A new analysis is presented for the carrier-to-noise power with non-subtractive phase dithering.
