Abstract
Even though the hardware complexity is reduced and precision is increased in the DDFS, the obtained signal is in no match with the ideal signal. This is because of the non-linearity of DACs present in the DDFS architecture. The conventional DDFS architecture doesn´t account for the non-linearity of DAC which deteriorates the quality of the signal. This reduces the SNR and SFDR of the signal. This error can be reduced by the optimizing the values using Genetic algorithm.
