Design of a 12-bit 200-MSps SAR Analog-to-Digital converter. University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS). Author : Luca 

Chapter 2 discussed the basics of the SAR ADCs and their components such as the CDAC or the comparator in detail. Based on these fundamentals, Chap. 3 will present current research topics in the field of SAR ADCs. Generally, the core circuitry of the new SAR ADC should operate from a significantly lower supply voltage compared to the input voltage range. 3 Successive-approximation-register (SAR) analog-to-digital converter (ADC) design (5) Targeting the test and measurement application, this section includes many topics relevant to designing with SAR ADC devices. 17:19. 4.1 Determining a SAR ADC’s Linear Range when using Operational Amplifiers.

Chapter 3 presents the different architectures of SAR ADC and introduces sub-modules of the SAR ADC. A successive-approximation ADC is a type of analog-to-digital converter that converts a continuous analog waveform into a discrete digital representation using a binary search through all possible quantization levels before finally converging upon a digital output for each conversion. Transistor Level Design. The ADC consists of 5 major blocks - Sample/ Hold block, comparator, SAR Logic block, 8-bit DAC and the timing block. Each block is explained below.

The SAR ADC does the following things for each sample: The analog signal is sampled and held. For each bit, the SAR logic outputs a binary code to the DAC that is dependent on the current bit under scrutiny and the previous bits already approximated. The comparator is used to determine the state of the current bit.

Since the proposed design was made completely differential and hence reduced the noise parameter SNDR significantly.
