Bit, 15Msps SAR ADC . The . LTC ® 2387-16is a low noise, high speed, 16-bit 15Msps successive approximation register (SAR) ADC ideally suited for a wide range of applications. The combination of excellent linearity and wide dynamic range makes the LTC2387-16 ideal for high speed imaging and instru-mentation applications.

The SAR ADC is the commonly used architecture for data acquisition systems that are widely employed in medical imaging, industrial process control, and optical communication systems. In these applications, we usually need to digitize the data generated by a large number of sensors.

SAR ADC is found to lay the foundation for the test channel construction. The logic structure of SAR ADC is built by MATLAB software to verify its feasibility. Successive Approximation Register (SAR) based ADC consists of a sample and hold circuit (SHA), a comparator, an internal digital to analog converter (DAC), and a successive approximation register. When the ADC receives the start command, SHA is placed in hold mode. 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.

A summary indicates that the CS scheme shows compelling features for LVLP applications.

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.

Understanding SAR ADCs: Their Architecture and Comparison with Other ADCs. 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.

The comparator noise and settling error from C-DACs limit the performance of a SAR ADC [2]. Implementation of a 200 MSps 12-bit SAR ADC Department of Electrical and Information Technology, Faculty of Engineering, LTH, Lund University, June 2015. Implementation of a 200 MSps 12-bit SAR ADC Victor Gylling Robert Olsson V.Gylling & R.Olsson Master’s Thesis Series of Master’s theses Department of Electrical and Information Technology 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 . In the system of the present invention, the sampling capacitor can be the actual capacitive redistribution digital-to-analog converter (CapDAC) used in the SAR ADC itself, or a separate capacitor array.

The resolution of the ADC depends on the number of bits in the SAR. SAR IC converters are available in sizes from 8 to 18 bits—the greater the bit count, the greater the resolution and accuracy.
