Millimeter Wave Transceiver Design in CMOS Technology

Abstract

The thesis is divided into six chapters as listed below: Chapter 1

This chapter gives an introduction about traveling wave oscillators and highlights their particular importance to imaging applications besides the motivation of the presented work in this thesis. Chapter 2

This chapter discusses the system level requirements of the proposed transceiver to be used in skin and breast cancer detection. It includes the architectures of the main building blocks. A link budget is proposed. Chapter 3

This chapter introduces the concept of distributed amplifiers/oscillators with emphasis on transmission line-based oscillators and showing case of different known structures like Distributed Wave Oscillator, Rotary Traveling Wave Oscillators (RTWOs) and Standing Wave Oscillators (SWOs). The advantages and disadvantages of each architecture are highlighted. Chapter 4

This chapter includes the design of the RTWO and investigation of different transmission line architectures to provide the best performance. The used transmission line physical properties will be discussed. It includes design of distributed gain stages and studying their loading effect on the oscillator frequency. Oscillator model and simulation results are provided. Chapter 5

This chapter discusses the transistor level design of the rest of transceiver chain including the output buffers, mixer and the requirements of needed antennas. Physical implementation is carried out for most of the blocks besides post-layout simulations. Layout considerations and system top level assembly are discussed.
