Some Numerical Issues in Oscillator Noise Computation

Some Numerical Issues in Oscillator Noise Computation

The time-averaged spectral density of noise in oscillators can be computed by frequency-domain analysis of the time-varying linear system generated from linearizing about the oscillator's periodic steady state. When computing the component of the noise that is usually referred to as phase noise, there is a numerical difficulty that can be partially resolved by computing certain matrix eigenvectors. In this talk I will describe the difficulty and a resolution that is usually effective.
