1. Linear Transmitter Design Using Nonlinear Analog Circuits
Abstract : This dissertation deals with analog techniques at both the architecture and circuit design levels for designing power efficient linear radio-frequency (RF) transmitters. The use of nonlinear analog integrated circuits to implement certain critical signal processing functions for the multiplicative feedback and LINC techniques is investigated with the aim of improving the system performance in terms of complexity, linearity and power efficiency.

2. High-Temperature Analog and Mixed-Signal Integrated Circuits in Bipolar Silicon Carbide Technology
Abstract : Silicon carbide (SiC) integrated circuits (ICs) can enable the emergence of robust and reliable systems, including data acquisition and on-site control for extreme environments with high temperature and high radiation such as deep earth drilling, space and aviation, electric and hybrid vehicles, and combustion engines. In particular, SiC ICs provide significant benefit by reducing power dissipation and leakage current at temperatures above 300 °C compared to the Si counterpart. READ MORE

3. Reconfigurable Analog to Digital Converters for Low Power Wireless Applications
Abstract : The commercialization of Marconi’s radio transmission and reception, along with the development of integrated circuits in the 1960’s have facilitated many new consumer products for wireless communication, where the mobile phones or handsets are one. These handsets started out as a portable phone, mounted in cars, and have with time added additional services as Short Message Service, and have today become a media center with global positioning, and high-speed internet connection.
