Steady state (electronics)
Encyclopedia
In electronics, steady state is an equilibrium condition of a circuit or network that occurs as the effects of transients are no longer important.
Steady state determination is an important topic, because many design specifications of electronic systems are given in terms of the steady-state characteristics. Periodic steady-state solution is also a prerequisite for small signal dynamic modeling. Steady-state analysis is therefore an indispensable component of the design process.
) methods, are the best choice for most microwave circuits excited with sinusoidal signals (e.g. mixers, power amplifiers).

Time domain methods
Time domain methods can be further divided into one step methods (time domain sensitivities) and iterative methods (shooting methods). One step methods require derivatives to compute the steady state; whenever those are not readily available at hand, iterative methods come into focus.See also
