The SAR ADC does the following things for each sample: The analog signal is sampled and held. For each bit, the SAR logic outputs a binary code to the DAC that is dependent on the current bit under scrutiny and the previous bits already approximated. The comparator is used to determine the state of the current bit. Successive Approximation (SAR) ADC An Analog to Digital Converter (ADC) is a type of device which helps us to process the chaotic real-world data in a digital standpoint. In an SAR ADC the proof mass is a voltage provided by the DAC. It is compared to the input, corresponding to the test mass, by the comparator.

Figure 1 provides the basic block diagram, functionality, and common terminology for ADCs. This figure shows an analog signal applied to the input of the ADC, which then is converted to digital words at the sampling frequency (Fs) applied to the ADC clock. Figure 1 is a time domain representation of the ADC’s input and output signals. Figure 1. sar adc 앞의 증폭기에서는 일반적으로 증폭기와 sar adc 사이에 1차 저역 통과 필터를 배치하여 적절한 안정성을 제공합니다.

This paper will explain how the SAR ADC operates by using a binary search algorithm to converge on the input signal. It also explains the heart of the SAR ADC, the capacitive DAC, and the high-speed comparator. Unlike a pipelined ADC, the SAR architecture doesn’t have latency. The relatively high sample rate along with zero-latency makes the SAR ADC suitable for multiplexed data acquisition. In this article, we’ll first review the basic architecture of a SAR ADC and then take a look at one of its common applications.
