'''Small-signal modeling''' is a common analysis technique in [[electronics engineering]] used to approximate the behavior of [[electronic circuit]]s containing [[nonlinear device]]s with [[linear equations]]. It is applicable to electronic circuits in which the AC [[signal (electrical engineering)|signal]]s (i.e., the time-varying currents and voltages in the circuit) are small relative to the DC [[bias (electrical engineering)|bias]] currents and voltages. A small-signal model is an AC [[equivalent circuit]] in which the nonlinear circuit elements are replaced by linear elements whose values are given by the first-order (linear) approximation of their characteristic curve near the bias point.
