A basic semiconductor diode can operate in forward bias but it cannot conduct during reverse bias. The special type of diode that can conduct in reverse bias is referred to as a Zener diode. This diode can conduct in forward bias just like a normal diode. The junction for the Zener diode will be heavily doped. Because of this reason, it can work as normally as a basic junction in forwarding bias and can tolerate the reverse currents during reverse bias. The main purpose of it is to use in … [Read more...]
MOSFET as a Switch and Its Characteristics
MOSFET Switch is a metal oxide semiconductor device that consists of three terminals known as source, gate, and the drain. It comes under the classification of basic field-effect transistor (FET). The conduction is either dependent on the flow of electrons or holes as per the type of the channel. This makes the device to be unipolar. Other than three terminals there exists one more type of terminal that is referred to as the substrate or the body but it is neither used in input nor output … [Read more...]

Basics of FET, Working Types and Its Applications
FET stands for the Field-effect transistor. These transistors are designed to overcome the drawbacks of the bipolar junction transistors. As the basic transistors have the junction of the emitter in the mode of forwarding bias this makes the device to operate at low impedance levels. This introduces considerable amounts of noise levels. FETs possess all the characteristics which can overcome the drawbacks of bipolar junction transistors and can be a good replacement for the vacuum tubes as well … [Read more...]
Basics of Common Collector Amplifier, Characteristics and Applications
A Common Collector Amplifier is formed from the basic Bipolar Junction transistor (BJT). Basically it is required to have four terminals so that two are preferred for the input and the remaining two is for output side. But it has only three terminals named as collector, base and the emitter. Among these terminals one is made common so that it can be connected on both sides of input as well as output. This leads to the formation of three configurations that are common base, common collector … [Read more...]
Common Emitter Amplifier Working, Characteristics and Applications
Common Emitter as an Amplifier is a configuration of the basic Bipolar Junction Transistor (BJT). As it consists of three basic terminals that are base, emitter and the collector but for the input and the output circuit connections it require minimum of four terminals. In order to overcome this drawback a terminal among those three terminals made common so that it behaves in common for both input and output circuitry connections. When emitter is made common to both input and output then it … [Read more...]
