@conference{10902/19505, year = {2012}, url = {http://hdl.handle.net/10902/19505}, abstract = {An investigation of the synchronization behavior of oscillators driven with multi-harmonic sources is presented. The occurrence of ultra-subharmonic synchronization is demonstrated, which gives rise to a multi-resonance behavior versus the fundamental input frequency. When this frequency decreases, instabilities arise in the low amplitude intervals of the multi-resonance curve, and both flip and Hopf bifurcation may delimit the stable synchronization intervals. The study provides a generalization of the theory of fundamentally locked oscillators to the case of oscillators driven with multi-harmonic signals. It is illustrated through application to an oscillator at 5.7 GHz.}, organization = {This work has been supported by the Spanish Government under contract TEC2011-29264-C03-01.}, publisher = {7th European Microwave Integrated Circuit Conference (EuMIC), Amsterdam, Netherlands, 2012, 274-277}, title = {Stability analysis of oscillators driven with multi-harmonic sources}, author = {Fernández Ruiz, Elena and Ramírez Terán, Franco Ariel and Suárez Rodríguez, Almudena and Sancho Lucio, Sergio Miguel}, }
