Low Phase Noise Signal Generation Utilizing Oscillators, Resonators, Filters, and Atomic Clocks
This talk will discuss the theory and design of a wide variety of oscillators offering the very best performance. Key features of oscillators offering the lowest phase noise available will be shown, for example: a 1.25GHz DRO produces -173dBc/Hz at 10kHz offset and a noise floor of -186dB and a 10 MHz crystal oscillator shows -123dBc/Hz at 1Hz and -149 at 10Hz. New printed resonators (and thereby filters) demonstrate Q’s exceeding 540 at 5GHz on PCBs and > 80 at 21GHz on GaAs MMICs. Alumina based resonators demonstrating Qs >200,000 at X band have also been produced. Tunable versions (1%) have recently been developed. The author also conducted a course on oscillators including a lab class kit at IMS 2009-11. The kit also produced state-of-the-art performance with flicker noise corners around 200Hz. The methodology behind this course will be described. Theory and 5 experiments on the same day was part of the reason for success.
Jeremy Everard obtained his BSc Eng. from the University of London, King’s College in 1976 and his PhD from the University of Cambridge in 1983. He worked for six years at the GEC Marconi Research Laboratories, M/A-Com and Philips Research Laboratories on Radio and Microwave circuit design. He taught RF/Microwave Circuit design, Opto-electronics and Electromagnetism at King’s College London for nine years while leading the Physical Electronics Research Group. He became University of London Reader in Electronics at King’s College London in 1990 and full Professor of Electronics at the University of York in 1993. In 2007, he was awarded a five-year research chair in Low Phase Noise Signal Generation sponsored by BAE Systems and the Royal Academy of Engineering. His research interests include: theory and design of low noise oscillators, all optical self-routing switches, ultra-fast opto-electronic detectors and mixers for THz applications,and distributed fiber optic temperature sensors. He has published papers on: oscillators, amplifiers, resonators and filters, all optical switching, optical components, optical fiber sensors and mm-wave optoelectronic devices and a book on ‘Fundamentals of RF Circuit Design with Low Noise Oscillators’. He is a member of the IET, London, the IEEE Solid State Circuits Society (SSCS), and the IEEE Microwave Theory and Techniques Society.
