I am working on BIST of Digital to Analog Converters and I need to generate a signal on-chip to measure SFDR and SINAD ratio of DAC.
Generally SFDR of DAC is defined with assuming input as digital bit pattern for monotonic sine wave. But I want to know which signal will prove to be worst case input for DAC such that a DAC giving reasonable SFDR for that signal will always be considered to work for other type of input bit-patterns.
Also plz tell me are there any other methods to calculate SFDR except the conventional frequency spectrum and FFT calculation based one.
