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. It also explains the heart of the SAR ADC, the capacitive DAC, and the high-speed comparator.

• SAR designs with a post-multiplexer filter result in a system with settling-time issues almost identical to the ΔΣdesign, but with higher noise. SAR ADC를 구성하는 주요 블럭은 TAH (track-and-hold,) DAC (digital-to-analog converter), comparator 그리고 digital control block 입니다. 이 중에서 아날로그 관점에 잘 살펴봐야 할 블럭은 track-and-hold와 comparator 입니다. 앞으로 하나씩 살펴보도록 하겠습니다. 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. 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.

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. Section 3 discusses the basics of SAR ADCs and Modifications. Section 4 explains the implementation of split DAC and split SAR ADC using Cadence.

The delta sigma converter (ΔΣ-converter or ΣΔ-converter) is one of the most used methods for high-resolution analog to digital converters (ADC) at a certain speed. Nowadays it is often included in the microcontrollers displacing the typical SAR standard converter.. The working principle of the ΔΣ-adc is the charge balancing, by using incremental steps.

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.

The SAR ADC has an internal DAC, which at every clock converts the 8-bit SAR Logic output into discrete signal, which is fed into the comparator. This feedback is used to decide the next bit of the SAR output. In the project, a Charge redistribution DAC with binary weighted capacitance [3] configuration is used.

• SAR-based systems often require low-pass filters on each channel,increasing power and cost. • ΔΣsystems generally offer greater accuracy and lower noise floor. • SAR designs with a post-multiplexer filter result in a system with settling-time issues almost identical to the ΔΣdesign, but with higher noise. Application of ADC ADC are used virtually everywhere where an analog signal has to be processed, stored, or transported in digital form. Some examples of ADC usage are digital volt meters, cell phone, thermocouples, and digital oscilloscope. analog-to-digital converter that converts a continuous analog waveform into a discrete digital representation via a.SAR Analog-to-Digital Converter in medical application such as pacemaker. Studies an ultra-low power 10-bit SAR ADC in 65 nm technology is designed.

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 (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). This
