Web12 Apr 2024 · SAR ADC S The working principle of SAR ADCs follows a successive digital approximation of the analog input voltage. To illustrate this process, consider the SAR ADC schematic shown in Fig. 1, which uses binary weighted CDAC, bottom plate sampling and unit capacitor u. cThe SAR-digital block is a state machine that controls all the conversion ... WebSNR is a measure of the broadband noise introduced into the signal from the ADC and the sampling process. SNR compares the magnitude of the input sine wave to the sum of all other frequencies, except those representing harmonics of the fundamental. Total harmonic distortion (THD) is the ratio of the fundamental to the sum of the harmonics.
