The diode is a nonlinear device. The important concept of piecewise-linear modeling will be applied to the diode in most applications. The concept of small-signal and large-signal models will be introduced.
The diode is used in many important non-amplifier applications. A few of these will be considered later in this part.
Junction diodes have many applications in various electronic circuits and systems such as rectifiers, voltage regulators, varactors, clippers, limiters, photodetectors, LEDs and so on. This part of the course discusses them in detail.
