From small LED drivers to rectifiers to Switch Mode Power Supplies (SMPS), the diode is a key component in each of those everyday appliances. They are also used in charging LED indicators and reverse polarity protection circuits in router chargers and many more; diodes are used everywhere, but this little device often does not get […]

The signal diode is a semiconductor device that is based on the PN junction theory, previously described in the article. It is the simplest, non-linear semiconductor device and is found in almost every electronic circuit. As we learned from the previous article, two currents can flow in the PN junction namely diffusion and drift current. […]

PN Junction Introduction It is better to briefly revise the basic semiconductor theory before starting the PN junction theory. As we know, the N-type semiconductor has electrons as majority carrier and holes as minority carrier. The impurity in N-type semiconductor is a donor and has a bound positive charge which neutralizes majority electrons as a […]
