What is SAR ADC algorithm?
SAR is an abbreviation for Successive Approximation Register. This is a particular type of Analog to Digital converter. A SAR ADC uses a series of comparisons to determine each bit of the converted result.
What is the function of SAR?
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.
What is SAR in VLSI?
Successive Approximation Register (SAR Logic) The SAR operation is based on binary search algorithm. A SAR logic takes 10 cycles (8bits + 2 extra cycles) to generate one output. Hence, if the sampling rate is 200KHz, 2MHz of clock is required for SAR. In this logic, the bits are represented by the registers D7-D0.
Which are the block of SAR ADC?
As seen in Fig. 2, the main blocks of this proposed SAR ADC are level shifters, D/A converter, comparator and SAR control logic circuit.
What is the function of an ADC?
An analog-to-digital converter (ADC) is used to convert an analog signal such as voltage to a digital form so that it can be read and processed by a microcontroller. Most microcontrollers nowadays have built-in ADC converters.
What are the advantages of ADC?
Advantages of ADC The advantages of Analog to Digital Converter include: Flash ADCs are the fastest compared to the other Analog to Digital Converter. Compared to other converters, Sigma Delta ADCs offer high resolution at low-cost. Successive Approximation ADCs operate at high speed and are more reliable.
Which of the following is a block of SAR ADC?
What are types of ADC?
There are really five major types of ADCs in use today:
- Successive Approximation (SAR) ADC.
- Delta-sigma (ΔΣ) ADC.
- Dual Slope ADC.
- Pipelined ADC.
- Flash ADC.
What is ADC and its types?
Observe that in the figure shown above, an Analog to Digital Converter (ADC) consists of a single analog input and many binary outputs. In general, the number of binary outputs of ADC will be a power of two. There are two types of ADCs: Direct type ADCs and Indirect type ADC.
