cations, the device is biased at some DC value. There are many cases where diodes are operated with small AC signals around a DC offset voltage. In such a case, conven-tional linear small-signal diode models are usually used. In forward bias, a diode is modeled with two components: a diode resistance rd, and charge storage capacitance CSC.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 ...
