Steady state (electronics)


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 is reached after transient state has subsided. During steady state, a system is in relative stability.
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.

Calculation methods

Steady state calculation methods can be sorted into time-domain algorithms and frequency-domain algorithms methods, are the best choice for most microwave circuits excited with sinusoidal signals.

Time domain methods

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