Subharmonic phase‐lock criteria for a class of weakly non‐linear high‐order oscillators

摘要

AbstractSubharmonic frequency entrainment of high‐order weakly non‐linear oscillators is investigated. For the class of circuits considered, equations are first derived which provide the first approximation values for the amplitudes and phases of the two main spectral components of the steady‐state waveform. Necessary and sufficient stability criteria are then derived in explicit from.The example worked out (a negative conductance double‐tuned oscillator) shows the efficiency and ease of use of the proposed
