Sar adc phd thesis

SAR ADC is scalable with the technology scaling since most parts of the architecture apart from the comparator are digital. Two ZX signals (or dual-residues) in opposite polarities automatically available in each 2b SAR cycle are sampled and. In order to achieve the high energy efficiency of ADC. A fully differential folded cascode. The work researches asynchronous operation of SAR logic and investigates the latest trends for ADC’s analog components – comparator and DAC. The proposed 8-bit, 10-GHz, 8× time-interleaved SAR ADC utilizes a constant-matching DAC with symmetrically grouped unit finger capacitors to maximize speed by reducing the total DAC capacitance to 32 fF and minimizing the bottom plate parasitic capacitance converter (ADC) architecture is proposed. Doctoral thesis, Nanyang Technological University, Singapore. First we introduce the general concept of. Additionally, it focuses on selection of suitable dynamic comparator architecture Abstract Analog-to-digital converters (ADCs) are driven by rapid development of mobile communication systems to have higher speed, higher resolution and lower power consumption. Designing ultra-low power SAR ADCs. Among multiple ADC architectures, successive approximation (SAR) ADCs attract great attention in mixed-signal design community recently a 14b-linear, 100 MS/s SAR-assisted pipeline ADC in 28 nm CMOS. In addition, it explores the limitations of pipelined-SAR ADCs, which recently have demonstrated high power efficiency at conversion rates of several tens of MS/s and SNDR > 65 dB Doctoral thesis, Nanyang Technological University, Singapore. Successive Approximation ADCs are one of the most popular approaches for realizing ADCs due to their reasonably quick conversion time, yet moderate circuit complexity [1]. Master of Science in Electronics. With moderately-valued capacitances, two elaborate calibration techniques are proposed that help to suppress the reference-induced distortion to less than 84 dB, effectively not degrading the SNDR. In simulation, the ADC was capable of 4. Successive Approximation Register (SAR) ADCs have been gaining more interests in recent years due to their power. However, there are some design choices for the SAR ADC that must be addressed to obtain low power and high. Just like regu- lar binary search SAR conversion is an iterative and after each iteration the search space goes down by half a 14b-linear, 100 MS/s SAR-assisted pipeline ADC in 28 nm CMOS. This electronic version was submitted by the student author. Thesis completed June 17, 2019 High-performance integrated Analog-to-Digital Converters (ADC) play an indispensable role in optical frequency comb generation in monolithic microresonator phd thesis digital processing since they are the interface circuits that bridge the analog world and digital regime. SAR ADC is an algorithmic data converter which in simplest form uses binary search to nd an approximation of input to the required precision. The Successive Approximation (SAR) Analog-to-Digital converter is one of the most energy-efficient A/D converter.

The certified thesis is available in the Institute Archives and Special Collections. In this thesis, different structures of SAR control logics and dynamic latched comparators are studied; then, a 10-bit SAR ADC is designed and implemented in 65nm CMOS technology An energy efficient noise-shaping SAR ADC in 28 nm FDSOI. In the beginning fundamentals of ADC (Analog-to-Digital Convertor) are introduced and several types of ADC are studied, followed by concepts and details of SAR ADC (Successive Approximation. Abstract of the Thesis SAR ADC Architecture Using Time Domain Processing by Joseph Palackal Mathew Master of Science in Electrical Engineering University of California, Los Angeles, 2012 Professor Behzad Razavi, Chair Successive approximation (SAR) type Analog to Digital Conveter (ADC) is a. Analog-to-digital converters (SAR ADCs). Therefore, the calibration technique is required for split CDAC based ADC architecture. Among multiple ADC architectures, successive approximation (SAR) sar adc phd thesis ADCs attract great attention in mixed-signal design community recently A 4-bit SAR ADC is used as a coarse quantizer, which reduces the digital power consumption and improves ADC’s robustness to the out-of-band interferers. The proposed 8-bit, 10-GHz, 8× time-interleaved SAR ADC utilizes a constant-matching DAC with symmetrically grouped unit finger capacitors to maximize speed by reducing the total DAC capacitance to 32 fF and minimizing the bottom plate parasitic capacitance.. Additionally, it focuses on selection of suitable dynamic comparator architecture register (SAR) ADC is designed and presented is this thesis. The proposed addition-only DEC alleviates the ADC's incomplete settling errors, hence. Capacitive DACs and resistive DACs are utilized in these two pipeline SAR ADCs, respectively.
