What is a Gunn diode A Gunn Diode is a microwave semiconductor diode designed to work in devices having microwave frequencies. Microwave Frequencies are electromagnetic radiation of tremendously high frequencies (THF), (maximum working frequency up to 3 THz, this depends on the material used in its structure). The most common materials used in their manufacturing…
Every student faces difficulty understanding the concept of Tunneling effect in the tunnel diode. Students are much confused about different types of diodes they encounter in their academics. We have already explained Photodiodes, Zener diode, Schottky Diode, LED etc. Now, we are going to explain about Tunnel diode, working operation, construction, and applications etc. What is…

Diode is an electronic device conduct current in one direction i.e. either in the forward direction or in the reverse direction. Today’s most commonly used diode is semiconductor diode. In our previous articles, we explain basic theory of semiconductors, P-n junction diode, and P-n junction diode characteristics etc. Here we are going to explain about Diodes…
Phase shift oscillator is an RC type oscillator whose output is fed back to its input through a phase shift network consisting of resistors and capacitors in a ladder network. In our last tutorials, we explain LC oscillator like Hartley, Colpitts etc, Wien bridge oscillator and crystal oscillator in detail. Here we are going to…
Earlier we have studied about oscillator and its types. Here we are going to cover Wein Bridge Oscillator, its circuit with and without using op-amp. In our previous articles, we have explained LC oscillators i.e. Hartley oscillator and Colpitts oscillator and Crystal oscillator in detail.

Crystal oscillator is an electronic oscillator used to create an electrical signal of precise frequency by using the vibrating crystal mechanical resonance made of piezoelectric material. In our previous articles, we explain Hartley oscillators and Colpitts oscillators in brief. Here we are going to explain crystal oscillator and its circuit diagram in brief. There are…
Hartley oscillator is a LC feedback circuit used to generate high-frequency waveforms or signals into which the oscillation frequency is determined by a tank circuit comprising of two inductors and one capacitor. In our previous article, we explain oscillator circuit and oscillator types in detail. In this article, we are going to explain Hartley oscillator and…
An oscillator is an electronic device which provides the source of a repetitive alternating current signal across its output terminal without needing any input because signal generated is usually of constant amplitude. Common signals generated includes clock signals, sound signals produced by video games, electronic beepers and broadcast signals by television and radio transmitters. In…
BJT and FET both are made up of different semiconductor materials mainly P type and N type. These transistors are basically used for the designing of oscillators, amplifiers, and switches. In our last articles, we explain in detail how to use a transistor as a switch, amplifier and as an oscillator. Here we are going…
