A general program for steady state, stability, and FM noise analysis of microwave oscillators

Two novel algorithms are presented for nonlinear autonomous circuit CAD. In the first, a symbolic simulator is used to calculated the possible oscillation frequencies of the circuit, and the high-level behavior of the oscillator is determined by the harmonic balance method extended to autonomous circuits. The second algorithm is based on the conversion matrix method, which allows simulation of nonlinear microwave oscillator phase and amplitude noise spectra with linear and nonlinear correlated noise sources.<<ETX>>
