'''Small-signal modeling'''<ref name=":0">{{Cite journal|last=Chakravorty|first=Pragnan|title=A Modified General Diode Equation|url=https://doi.org/10.1109/TCAD.2021.3116456|journal=IEEE Transactions on Computer Aided Design of Integrated Circuits and Systems}}</ref> is a common analysis technique in [[electronics engineering]] used to approximate the behavior of [[electronic circuit]]s containing [[nonlinear device]]s with [[linear equations]]. A major change in understanding of non-linear device modeling was brought in the year 2021<ref name=":0" /> where small signal modeling may no longer be required for the non-linear devices as a large signal model was introduced for this purpose. 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.
