Steady-state analysis of high-Q oscillator circuits by hybrid harmonic balance method

A new steady-state analysis method of high-Q oscillator circuits is proposed. An oscillator circuit is partitioned into the linear subnetworks containing high-Q resonators and the nonlinear subnetworks containing nonlinear active components, with the substitution sources respectively. The steady-state waveforms of the substitution sources are determined by the harmonic balance method. The steady-state responses of the linear subnetwork are calculated by the phaser technique and those of the nonlinear subnetworks are calculated by the time-domain approach. Good agreement has been obtained between the calculation and the measurement
