It is therefore essential to develop simple accurat e theories and design procedures to produce oscillators offering state of the art performance.\n\nThis talk will initially discuss the theory and de sign of a wide variety of oscillators offering the very best performance. Typically\, this is achieved by splitting the oscillator design into its c omponent parts and developing new amplifiers\, resonators and phase shifte rs which offer high Q\, high power handling and low thermal and transposed flicker noise.\n\nKey features of oscillators offering the lowest phase n oise 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 oscil lator shows -123dBc/Hz at 1Hz and -149 at 10Hz.\n\nNew compact atomic cloc ks with ultra-low phase noise microwave synthesizer chains (with micro Hz resolution) will also be briefly described to demonstrate how the long-ter m stability can be improved.\n\nNew printed resonators (and thereby filter s) demonstrate Qs exceeding 540 at 5GHz on PCBs and > 80 at 21GHz on GaAs MMICs. These resonators produce near zero radiation loss and therefore req uire no screening. L band 3D printed resonators demonstrate high Q (> 200) by selecting the standing wave pattern to ensure zero current through the via hole and new ultra-compact versions (4mm x 4mm) have been developed f or use inside or underneath the package. Alumina based resonators demonstr ating Qs >200\,000 at X band have also been produced. Tunable versions (1% ) have recently been developed.\n\nAs an academic\, the aim is to produce the state of the art through insight and understanding\, as well as to exp lain this to others. The author ran the first course on oscillators includ ing a lab class at IMS 09. This was repeated in 2010\, 2011. A battery pow ered lab kit offering 5 experiments with full theoretical and simulation s upport was provided. The kit also produced the state of the art performanc e with flicker noise corners around 200Hz. The methodology behind this cou rse will be described. Theory and 5 experiments on the same day was part o f the reason for success.\n\nThe next generation of oscillators will offer orders of magnitude improvement in performance. Our current attempts to d o this will be described.\n\nSpeaker bio: Jeremy Everard (M’90) obtained his BSc Eng. from the University of London\, King’s College in 1976 and his PhD from the University of Cambridge in 1983.
