TLDR
We propose an alternative architecture that allows a practical speed improvement of DDFS circuits by using a switched-capacitor interpolator inserted between the digital-to-analog converter (DAC) and the continuous-time output filter and which allows a relaxation of both the filter selectivity requirements and the DAC clock frequency.
