Nowadays, majority of circuits include some type of oscillator. They are present in all time-measurement and communication circuits. Type of the system defines required accuracy and/or frequency stability.
Additionally, for communication systems, also phase jitter is a key selective parameter. Parameters are weighted according to the system, where the oscillator is used. For many decades, crystal oscillators are selective choice for systems, where accuracy is required. In last ten years, progress in CMOS technology structures allowed development of MEMS and CMEMS oscillators, and also RLC resonator-based oscillators, which can replace crystal oscillators on many fields.
Focus of this thesis is on supply noise influence on phase jitter.
In the introduction, the thesis presents short history of oscillators and their end use. The second chapter describes different types of oscillators and compares their characteristics. Chapter three presents different jitter types. Measuring method, used equipment and set of tested oscillators is presented in chapter four. Measuring results and their interpretation is presented in fifth chapter. Last, sixth chapter, provides conclusions and directions for most appropriate use of oscillators.
