Jun 22, 2016 This work tries to fulfil these demands by implementing a Successive- Approximation-. Register (SAR) Analog-to-Digital Converter (ADC) in a 28

It also explains the heart of the SAR ADC, the capacitive DAC, and the high-speed comparator. The main target is to design an ultra-low power 10-bit SAR ADC operating at f s = 1kS/s. 1.3 Thesis outline In this thesis, Chapter 2 reviews the fundamentals of A/D conversion and performance metrics of A/D converter. Chapter 3 presents the different architectures of SAR ADC and introduces sub-modules of the SAR ADC. ubiquitous SAR ADC architecture and design can be used in all medical chips and devices. Based on the application and designed task for implant of sensors or chips, integrated circuit (IC) designers tend to propose a unique SAR design both in architecture and circuitry.

As a result, outstanding conversion linearity, high signal-to-noise ratio (SNR), high conversion speed, robustness, superb energy efficiency, and minimal chip-area are accomplished simultaneously. The first design is a 12-bit 22.5/45-MS/s SAR ADC in 0.13-μm CMOS process.

register (SAR) ADC exhibits signiﬁcantly high energy efﬁciency compared to other prevalent ADC architectures due to its good tradeoffs among power consumption, conversion accuracy, and design … simplicity and design specifications. SAR ADCs have a decent conversion speed (about 50kHz to 4MHz [13]) and take small overall chip area in comparison to flash ADCs, which are fast but take up a large area. SAR ADC design also flows well with the use of a serial output port due to the nature of the conversion method. Ohnhäuser F. (2015) Advanced SAR ADC Design.

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. 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.

It is known that on-chip passive charge sharing suffers from poor linearity due to the unregulated reference voltage during bit trials. This paper gives a detailed analysis for the reasons of poor linearity for passive-charge-sharing SAR ADCs The SAR architecture allows for high-performance, low-power ADCs to be packaged in small form factors for today's demanding applications. This paper will explain how the SAR ADC operates by using a binary search algorithm to converge on the input signal. It also explains the heart of the SAR ADC, the capacitive DAC, and the high-speed comparator. The main target is to design an ultra-low power 10-bit SAR ADC operating at f s = 1kS/s. 1.3 Thesis outline In this thesis, Chapter 2 reviews the fundamentals of A/D conversion and performance metrics of A/D converter.

Figure 2. 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.
