A phase compensation algorithm is used to compensate for the additional phase delay introduced by the multiplexed ADC, thereby producing an effect equivalent to a synchronously sampled ADC.
This design introduces the concepts of phase and phase compensation, compares the additional phase delay introduced between the input channels of an asynchronous sampling ADC and a synchronous sampling ADC, and provides an optimal algorithm to compensate for the phase introduced in an asynchronous sampling ADC Delay.
Measurements show how the phase compensation algorithm used in this design compensates for the additional phase delay introduced by multiplexed ADCs, resulting in a performance solution comparable to the simultaneous sampling ADC solution.
