@conference{10902/18187, year = {2019}, url = {http://hdl.handle.net/10902/18187}, abstract = {An analysis of self-injection locked oscillators using a slow-wave structure for phase-noise reduction is presented. This structure is the key component of a feedback network, added to an existing oscillator and providing a stable self-injection locking signal. The unit cell of the slow-wave structure is based on a recently proposed configuration, made up of an open-ended stub and a Schiffman section. A tuning capacitor is introduced as an additional parameter, enabling an adjustment of the structure response at the desired oscillation frequency. The circuit solutions are analyzed by means of a semi-analytical formulation that incorporates the results of an electromagnetic simulation of the structure. The formulation enables a prediction of multivalued parameter regions, inherent to the long delay, which are more controllable than in the case of continuous transmission lines. An analytical derivation of the phase-noise spectral density is presented, which relates the phase-noise reduction with respect to the original freerunning oscillator to the group delay of the self-injection network. The analysis and synthesis method has been applied to an oscillator at 2.75 GHz.}, organization = {This work was supported by the Spanish Ministry of Science, Innovation and Universities and the European Regional Development Fund (ERDF/FEDER) under the research project TEC2017-88242-C3-1-R.}, publisher = {Institute of Electrical and Electronics Engineers Inc.}, publisher = {IEEE/MTT-S International Microwave Symposium (IMS 2019), Boston, MA, USA, 2019, 456-459}, title = {Phase-noise reduction in self-injection locked oscillators using slow-wave structures}, author = {Pontón Lobete, María Isabel and Ramírez Terán, Franco Ariel and Herrera Guardado, Amparo and Suárez Rodríguez, Almudena}, }
