Abstract
This dissertation demonstrates the different issues of implementing TCXO in CMOS technology. The dissertation is divided into five chapters organized as follows:
Chapter One: This chapter is an introduction to crystal oscillators’ basics, importance of crystal oscillator frequency stability, and parameters.
Chapter Two: In this chapter, the factors that affect crystal oscillator frequency stability are discussed. Different methods used to enhance it are discussed. And, the proposed system architecture is presented
Chapter Three: In this chapter, the new method we implement for amplitude control is presented, explained, and analyzed. The circuit design of the amplitude controlled crystal oscillator in CMOS technology is presented. The main blocks of the amplitude controlled crystal oscillator are analyzed, designed, and simulated.
Chapter Four:
In this chapter, the temperature sensor basics are discussed. The main blocks are analyzed, designed, and simulated.
Chapter Five:
In this chapter, the system integration results are presented. Layout of the complete system architecture is shown.
Finally, the thesis ends by extracting conclusions and stating future work that might be done based on this work.
