<p> State-of-the-arts design, implementation, and optimization of Ultra-Low Power Radio Frequency Integrated Circuits (ULP RFIC) for medical, space, and mobile applications have been proposed. New approximated formulas in modeling of the circuits and systems for CAD development have been suggested which make the computer simulations more accurate. Algorithm optimizations for faster design time and possible automations compared to traditional and manual implementations are also offered that reduce the final release time of the products in a more systematic way. These design methodologies are based on advancements of IC fabrication in scaling to Nano-meter regimes, improvement of powerful software simulation tools especially at high frequencies, and manipulating novel ideas in development phases. Note that these design proposals are not only limited to space, biomedical, and mobile application; as a matter of fact, they can be used in any chip design and development ranging from smart watch to glasses and etc.</p><p> To have a comprehensive understanding of wireless system design and circuit implementation requires years of experiences and research on multi-disciplinary areas ranging from semiconductor at physic level, circuit analysis, software programming for simulation, test and automation purposes, architecture level, high frequency and RF behavior of components and many more. That is why it has been said the RF design is challenging and takes more years to become an expert on these areas. There are still huge shortages for RF and Analog engineers due to the challenges throughout the world both in industry and academia.</p><p> For the circuits presented in this dissertation, frequencies range from ISM band 2.4GHz for mobile application to 10GHz and 24 GHz in microwave applications. The detail analyses for implementations and simulations have been shown to verify the implementations. Optimizations are presented by extensive analysis and iterative simulations. Solutions and tips to simplify design flows are mentioned throughout the dissertation.</p><p> Chapters begin with introductions and motivations; next, detail discussion and investigation are presented in subsequent sections; finally summaries giving at the end of each chapter. At the end of dissertation, the possible future works and research orientation have been proposed.</p>
