The block diagram of the proposed design is illustrated as Fig. 1. Comparator Design for SAR ADC? Hey everyone, I'm a beginner trying to get into IC design, and I've been working on a design for my master's project for creating a 10-bit hybrid (Flash+SAR) ADC. 2019-08-06 · different types of ADC. Chapter 3 introduces the proposed SAR ADC structure and compares it to the conventional SAR ADC architecture. Chapter 4 elaborates the design considerations and shows the simulation results. At last, the conclusion and the future work are included in Chapter 5.

In the project, a Charge redistribution DAC with binary weighted capacitance configuration is used. Abstract: Together with the increasingly demanding DAC, the design of the comparator introduces a big challenge for the implementation of high resolution SAR ADCs. Therefore, several state of the art works investigated improved comparator architectures aiming for higher resolution.

Sample/Hold Circuit. The S/H circuit captures the input analog signal based on a sampling frequency. In the project, the sampling frequency is 200 KHz. Low power consumption device is always in demand. Systems that are powered by non rechargeable batteries such as medical implant devices require low power design. This system uses Analog to Digital Converter (ADC) as an interface between analog and digital domain. This paper presents a low power comparator used in designing of Successive Approximation Register (SAR) ADC. A simple topology of SAR ADC design consideration A typical SAR ADC consists of three components: DAC, comparator, and SAR logic. It has become a superior ADC topology with a good tradeoff between power consumption, speed, and resolution.
