Laser diodes are PN junction devices under a forward bias. LASER is an acronym for Light Amplification by Stimulated Emission…
The varactor also termed to as varicap, is a diode that behaves like a variable capacitor, with the PN junction…
Because of the very high input gate resistance of MOSFETs, MOSFET’s fast switching speeds, and the ease at which they…
The Metal oxide semiconductor FET (MOSFET) also known as the insulated-gate FET (IGFET) is similar to JFET but exhibits even…
The bipolar transistor has several disadvantages: it has low input impedance because of forward biased emitter junction, it has small…
By placing two PN junctions together we can create a bipolar junction transistor. In a PNP transistor the majority charger…
Multiplexers and demultiplexers are devices that route signals. A multiplexer also called a data selector takes one of several inputs…
A tuned amplifier operates over a band of frequencies centered on a resonant frequency. Its two main requirements are to…
Diodes are used in many applications for example diodes are employed in reverse-polarity protection, used in voltage regulators, etc. We…
A diode is a device that allows current to flow only in one direction. It is made from p-type or…
