Effect of DAC Deglitching on Frequency Response
Sample-and-hold circuits used in deglitching state changes of digital-to-analog converters should normally be time-constant limited during the sample or tracking period to prevent the buffer amplifier input from saturating, which results in undesirable slewing and distortion. This time-constant limiting keeps the sample-and-hold circuit operating linearly but adversely affects the frequency response, particularly when the sample period is small compared to the sampling period (sample + hold) as in multichannel multiplexing audio systems. The equivalent transfer function of the deglitching process is derived and the corresponding frequency response is plotted in a typical application. A method of frequency compensation of this effect is proposed.
