the SAR ADC consumes 53 nW power at a sampling rate of 1 kS/s, achieving 9.1 ENOB. The paper is organized as follows. Section II describes the ADC architecture. Section III presents the detailed circuit design of the ADC. The measurement results and comparison with previous works are shown in section IV, followed by conclusions in section V. II.

1. How Calibration works There are three main sub-blocks important in understanding how the Kinetis SAR module works. There is a capacitive DAC, a comparator, and the SAR engine that controls the module. Of those blocks, the DAC is most susceptible to variations that can cause linearity problems in

The basic schema of a SAR converter is: Precision SAR ADC Selection Table Device Resolution (Bits) Sample Rate (kSPS) No. of Input Channels Input Voltage (V) Interface Companion Drivers Companion References + Buffers Package ADS8688 16 500 8 –10.24 to 10.24 Serial SPI OPA2209 REF5040 + OPA376 TSSOP (38): 9.7 mm x 4.4 mm 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. 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的工作流程.

Capacitor DAC circuit As the name implies, the SAR ADC basically implements a binary search algorithm. Therefore, while the internal circuitry may be running at several megahertz (MHz), the ADC sample rate is a fraction of that number due to the successive-approximation algorithm. SAR ADC Architecture SAR ADCs. Successive-approximation-register (SAR) analog-to-digital converters (ADCs) are the workhorse products of the industry because they offer good resolution at high sampling rates.

2010-04-03 2015-12-28 T. Fiutowski ADC SAR layout considerations SAR (successive approximation register) architecture (6-bit example) •Power and area-efficient architecture – the same circuitry is used n-times (for n-bit ADC) to approximate the input voltage •Asynchronous logic – no fast clock needed for … 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]. 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 ADC is found to lay the foundation for the test channel construction.
