Simulation results also demonstrate that the proposed method does not affect accuracy. Both ADC operation modes achieve SNDR (signal-to-noise distortion ratio)

Furthermore, a dual-supply voltage scheme allows the. SAR logic to operate at 0.4 V, reducing the overall power consumption of the ADC by 15% without any loss 

This article explains the operation of the SAR (successive approximation register)-ADC (analog-to-digital converter). It providesa Applications of SAR ADC. As this is a most commonly used ADC, it's used for many applications like uses in biomedical devices that can be implanted in the patient, these types of ADCs are used because it consumes very less power. Also, many smartwatches and sensors used this type of ADC. SAR ADC Operation: Operation of a basic SAR ADC is based on binary search algorithm or “principle of a bal-ance”(Fig.2). III. BINARY SEARCH ALGORITHM This section explains the binary search algorithm which realizes N-bit resolution SAR ADC with N-step, and we assume that the analog input range is normalized from 0 to 2N −1.

Basic SAR ADC  voltage drivers for the first-stage SAR ADC and the remaining pipeline stages reduce the reference disturbance caused by high-speed switching operation of. 2 Nov 2004 SAR is an abbreviation for Successive Approximation Register.

It also means that S3 must be switched back to ground (Figure 8). The operation of the SAR-ADC based on charge redistribution All Texas Instruments TLV- and TLC-series sequential serial analog-to-digital converters perform successive approxima-tionbased on charge redistribution. This article explains the operation of the SAR (successive approximation register)-ADC (analog-to-digital converter).

This explains why these types of ADCs are power- and space-efficient, yet are rarely This article reports a power-efficient 8× time-interleaved (TI) 2.4-GS/s 10-bit successive-approximation-register (SAR) analog-to-digital converter (ADC). To optimize the circuit design in terms of power efficiency and conversion rate, several enhancement techniques are presented.

Reference voltage, VREF=5.0 V Average reference current, IREF=100 µA Resolution, N=12-bit Step 1: Calculation of maximum allowed series resistance in the reference path: Step-by-step procedure to design a reference circuit Reference Circuit Design for a SAR ADC in SoC, Rev 0, 03/2015 Freescale Semiconductor, Inc. 9 Figure 2: SAR ADC Input Network The sample and hold (S&H) operation is embedded in the DAC circuitry, and the sampling capacitor is sized to meet the noise requirements. With this configuration and correct sizing of the sampling capacitor, the SAR ADC can convert very high frequency signals (tens of MHz) without resulting in high power dissipation.
