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. This dissertation is brought to you for free and open access by the graduate school at trace: tennessee research and creative exchange it has been accepted for multi-channel analog to digital converters (adcs) are required where signals from multiple sensors can be digitized successive approximation adc. In recent years, there has been a growing need for successive approximation register (sar) analog-to-digital converter in medical application such as pacemaker the demand for long battery life-time in these applications poses the requirement for designing ultra-low power sar adcs this thesis work initially. The supply voltage of the sar adc is decreased to 06 v to fit the low voltage and low power require- ments of biomedical systems  qin l research and design of 11-bit sar adc based on reused terminating capacitor switching procedure master thesis, zhe- jiang university, 2012  yu m, wu l, li f an 8 bit 12. Thesis abstract modern portable and wireless applications are driving analog-to- digital converters (adcs) design towards higher resolution and data rates sar adc therefore, the calibration technique is required for split cdac based adc architecture this work proposed an on chip histogram-based digitally assisted. Abstract this paper presents a functional design and modeling of a successive approximation analog-to-digital converter (adc) and its application in the conditioning circuit of the vibra- tion energy harvester the paper published on bmas'09 highlighted the necessity of a smart digital control to cali- brate the system.

Many wireline communication systems are moving toward a digital based architecture for the receiver that requires a front-end high-speed adc this thesis proposes a two-level time- interleaving topology for realizing such an adc, comprising front-end time-interleaved sub- rate track-and-holds each followed by a. This thesis presents a number of data conversion related circuit and algorithm techniques to reduce the power consumption of the cmos image sensor system- on-a-chip (soc) the first part of this thesis focuses on energy e fficient successive-approximation-register (sar) analog-to-digital converter (adc) architectures. Flash adc output is multiplexed to resolve msbs of the sar channels because the full-speed flash adc does not suffer from timing-skew errors, the flash adc output is also used as the timing reference to estimate the timing-skew of the sar adcs thesis supervisor: anantha p chandrakasan.
In this thesis, a systematic design methodology for a successive approximation analog-to-digital converter is presented with emphasis on the analog design reuse techniques a general multiple abstraction simulation environment is developed in vhdl-ams to describe and simulate the whole mixed adc blocks. Design of integrated circuits has become more challenging this thesis presents detailed design of the critical analog circuit blocks of the pipeline adc, covering two fabricated 130-nm 440- ms/s programmable 5-8-bit adc prototypes for a sar receiver due to their flexibility, the adcs can be optimized for.
Analysis and design of successive approximation adc and 35 ghz rf transmitter in 90nm cmos a thesis presented to the academic faculty by saravanan t k in partial fulfillment of requirements for the degree master of science in school of electrical and computer engineering georgia. Washington state university august 2008 chair: george s la rue this thesis presents an implementation of a self-calibrating low-power 16-bit 500 ksps charge redistribution successive approximation register based analog-to-digital converter (cr adc) to be used with a sensor integrated circuit (ic) built for neuro.
