After the development of the first point-contact transistor, the phototransistor was invented by one of the teams at Bell Labs. At that time, a large number of developments were being started. Even though the phototransistor history is not publicized like other early developments of semiconductors, but it was certainly a very significant development. The first invention of this transistor was announced on March 30th, 1950. This article discusses an overview of a phototransistor and its … [Read more...]
What is Gunn Diode : Construction & Its Working
In GaAs semiconductor materials, the electrons are present in two states like high mass low velocity & low mass high velocity. By the demand of an adequate electric field, the electrons are forced to move from a low mass state to a high mass state. At this specific state, electrons can form a group & moves at a consistent rate that can cause to flow current in a series of pulses. So this is known as Gunn Effect which is used by Gunn diodes. These diodes are the best and most frequently … [Read more...]

What is SMD Resistor : Construction & Its Working
Surface-mount technology or SMT-based components like resistors; capacitors, etc are used in huge quantities. SMT is an alternative to through-hole (TH) PCB design. SMT is a process where the electrical components are placed on a PCB (printed circuit board) directly. So, the process of mounting a component in this way is known as SMD (surface-mount device). At present, most industries like consumers, electronics are using this technology because this technology improves manufacturing, … [Read more...]

What is a Voltage Follower : Circuit & Its Working
We all know that an operational amplifier is the analog type of circuit that considers differential voltage as input and provides a single-ended voltage as output. These op-amps are mainly employed in the voltage follower circuits. But the arrangement of the op-amp in the voltage follower imposes high risk and capacitive stacking of oscillations. These huge loads show more impact on the operational amplifier stability dependent applications. So, let us know how the arrangement can be done in a … [Read more...]
What is Gate Turnoff Thyristor & Its Working
"Thyristor" is a semiconductor device that is popularly used as a switch in power circuits. With alternating layers of P-type and N-type materials, the thyristor is designed as a four-layered structure. It is available as both two-lead and three-lead designs. The three-lead design of the thyristor consists of an anode, a cathode, and a Gate lead. The thyristor usually starts conducting when the gate lead is triggered with the current and once turned ON, the thyristor conducts continuously until … [Read more...]
What is Shunt Capacitor : Working & Its Advantages
Capacitors' invention was initiated in the beginning days of electricity. In the initial days of development, capacitors were called condensers. This term was primarily utilized for the objective of high-power applications by Alessandro Volta in the year 1782. Thereafter, the term condenser was not in usage because of the complicated meaning of steam condenser and replaced by the name ‘capacitor’ in the year 1926. Now, this article provides a clear analysis of one foremost type of capacitor … [Read more...]
