20-stage pipelined ADC with radix-based calibration

Creator:: Yun, Chong Kyu
Abstract:: A radix-based calibration technique was previously proposed with a two-stage algorithmic analog-to-digital converter (ADC). The objective of this work is to verify the capability of radix-based calibration for a true multi-stage ADC. In order to prove the idea, a single bit-per-stage, 20-stage pipelined ADC is designed in a 0.35-μm CMOS...

5th-Order Elliptic LPF Using Passive Charge Compensation Technique (PCC) Design

Creator:: Tsai, Cheng H.
Abstract:: The passive charge compensation (PCC) technique was introduced for switched capacitor (SC) circuit to increase the slew rate and enhance the linearity performance, as PCC techniques are used on the Delta-Sigma modulator (DSM) in ADC circuitry. The PCC technique of the project was applied to the design of a SC...

802.11 Channel Switching for High-Definition Video Streaming

Creator:: Sullivan, Erin
Abstract:: As screen resolution and video decoding capability have increased, high-definition (HD) video in resolutions as high as 1920 x 1080 is rapidly becoming the standard. Ad-hoc streaming of HD video over 802.11 wireless networks, e.g., streaming from a mobile device to a television, is convenient for users, but is hampered...

A 1V 40mA Fast Transient Capless LDO with 7uA Quiescent Current in 180nm CMOS using Ring Amplifier with Adaptive Damping

Creator:: Xiao, Bohui
Abstract:: Ring amplification has emerged as an efficient technique to drive large capacitive loads in switched capacitor circuits. We propose circuit techniques to demonstrate the first application of a ring amplifier in a non-capacitive feedback system of a LDO. These techniques enable a simple cap-less LDO structure in 180nm CMOS that...

A 2.4GHZ direct conversion mixer with offset cancellation

Creator:: Schmidbauer, Hardy
Abstract:: Dynamic DC offset is one of the biggest problems preventing the implementation of single chip receivers. This thesis presents a 2.4GHz downconversion mixer designed to work with adaptive DC offset cancellation for a fully integrated direct conversion receiver. Offset can be removed by dynamically changing the PFET load bias in...

A 400Mb/s 850nm FSO Link based on CMOS Integrated Receiver for Hybrid WiFi and Optical Femtocells

Creator:: Chen, Siyuan
Abstract:: The increasing demand for higher data-rates is challenging to satisfy with spectrum-deﬁcient indoor WiFi networks. A novel hybrid WiFi Free-Space Optical (WIFO) system has been proposed to enhance the wireless capacity of indoor WiFi networks. In this thesis, an integrated optical wireless receiver is designed and integrated in 65-nm CMOS...

A 5 GHz Wi-Fi Receiver Front End with 4x80 MHz Channels for a High Accuracy Indoor Localization System

Creator:: Gray, Kyle L.
Abstract:: The ability to accurately locate people and objects indoors will enable opportunities for control and automation of indoor environments. Current indoor localization solutions require dedicated hardware which must be custom tailored to each application. There are large technological, societal, and economic benefits in developing a more general purpose system that...

A base control Doherty power amplifier design for improved efficiency in GSM handsets

Creator:: Ferwalt, Darren W.
Abstract:: In cellular telephones, RF power amplifiers consume a significant part of the total phone current. Reducing the average PA current will extend battery life. In GSM systems the handset is commanded by the base station to transmit at power levels lower than full power much of the time. A Doherty...

A Blockchains-Enabled Protocol for Distributed IoT Resource Sharing On-Demand

Creator:: Al-kalbani, Mohamed A.
Abstract:: In this thesis, we propose a Blockchain-based distributed protocol for enabling deployment of dynamic, on-demand IoT networks. Specifically, the proposed protocol leverages Blockchain technology to: (i) enable distributed and secure authentication, registration, and management of IoT devices; (ii) provide fast discovery of IoT resources and scalable and secure instantiation of...
