Abstract :
This paper introduces a new analytical model for the study of interpolation waveforms in time-averaging interpolative digital to analogue converters (DACs). This analytical model reveals some important phenomena about the interpolation process and can be used to determine the effects of varying individual interpolation waveforms on the overall performance of DACs. This allows strategies to be developed for minimising interpolation noise and can also be used to enhance the performance of large number of interpolation schemes
