Periodic AC and Periodic Noise in RF Simulation for Electronic Circuit Design

This overview highlights the main steps to come to Periodic AC and Periodic Noise simulation in RF simulation. A distinction is made between forced oscillators and free oscillators. Noisy elements contribute in various ways to the overall noise effect. When dealing with free oscillators, phase noise is most important. In the case of white and coloured stochastic noise sources, the spectrum of the (stationary) autocorrelation of the phase-shifted function can be determined by summing the effects of all independent noise sources. In general one has to take the nonlinear way, in which the phase shift function changes with time, into account.
