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. Microcontrollers commonly use 8, 10, 12, or 16 bit ADCs, our micro controller uses an 8 or 10 bit ADC.

SAR operation (4-bit ADC example) Notice that four comparison periods are required for a 4-bit ADC. Generally speaking, an N-bit SAR ADC will require N comparison periods and will not be ready for the next conversion until the current one is complete. 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. First, a pre-defined bypass window, introduced by the customized non-binary DAC, is used to modestly reduce the SAR ADC. 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.

All capacitors have binary weighted values, i.e SAR ADC Conﬁguration: An SAR ADC is composed of a sample hold circuit, a comparator, a DAC, SAR logic circuit and timing generator (Fig.1). SAR ADC Operation: Operation of a basic SAR ADC is based on binary search algorithm or “principle of a bal-ance”(Fig.2).
