SAR ADCs provide up to 5Msps sampling rates with resolutions from 8 to 18 bits. The SAR architecture allows for high-performance, low-power ADCs to be packaged in small form factors for today's demanding applications. This paper will explain how the SAR ADC operates by using a binary search algorithm to converge on the input signal.

The asynchronous SAR ADC proposed in this invention only needs a single external clock with a frequency equal to the sampling frequency. FIG. 1 depicts a block diagram of a prior art SAR ADC. The SAR ADC 1 is an n-bit ADC comprising a sample and hold (S&H) block 2 , a comparator 3 , a control block 4 , an n-bit DAC 5 , a first input/output (I/O) 6 , and a second input/output 7 .

SAR ADC Architecture Although there are many variations for implementing a SAR ADC, the basic architecture is quite simple (see Figure 1). The analog input voltage (V IN) is held on a track/hold. To implement the binary search algorithm, the N-bit register is first set to midscale (that is, 100 .00, where the MSB is set to 1).

The ADC Successive Approximation Register (ADC_SAR) component provides medium-speed (maximum 1-msps sampling), medium-resolution (12 bits maximum), analog-to-digital conversion. Translated documents are for reference only. We recommend that you refer to the English-language version of a document if you are engaged in development of a design.

Therefore, a SAR ADC needs at least n+1 clock cycles to convert an analog input to the ADC to a result, where n is the number of bits of the ADC. How it Works.
