What we would like to do is to see if we can find a linear relationship between \(v_{s}\) and \(i_{s}\), which we could use in our signal analysis. There are two ways we can attack the problem: a graphical approach, and a purely mathematical approach. A small-signal diode definition is; a type of PN junction diode which functions on low voltage signals. This is a small non-linear semiconductor diode normally used in electronic circuits. The junction area of this diode is very small so, this junction is capable of less charge storing & low capacitance. This diode has a high switching speed ...
