Abstract: Successive-approximation-register (SAR) analog-to-digital converters (ADCs) represent the majority of the ADC market for medium- to high-resolution ADCs. SAR ADCs provide up to 5Msps sampling rates with resolutions from 8 to 18 bits.

ADC is an important module in a whole digital processing system getting information from nature world. SAR ADCs of medium sampling rate (10M-500M Hz) moderate resolution (6-12 bits) are wildly used, because SAR ADC has several advantages. Firstly, SAR can benefit from the development of scaled CMOS proximation Register (SAR) technique. This technique uses binary search method.

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.

The analog input voltage (VIN) 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'). 2013-03-01 This paper describes design and implementation of 10-bit, 2MS/s split SAR ADC using 0.18um CMOS technology. Section 2 discusses the SAR ADC review.

The SAR ADC is presented as the ADC that is most frequently used in industrial applications, because it provides a high resolution (12–18 bit) at a medium sample rate (around 1 MSPS). This chapter therefore presents design and architectural basics and details regarding the components of a SAR ADC [1].

SAR ADC Architecture.

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 SAR ADC driver circuits have op-amps (A 1 and A 2) that separate the ADC from their signal sources (Figure 1).

A successive-approximation ADC is a type of analog-to-digital converter that converts a continuous analog waveform into a discrete digital representation using a binary search through all possible quantization levels before finally converging upon a digital output for each conversion.
