Classification of Power Amplifiers: Classification of Power Amplifiers are primarily divided into two categories viz. audio power amplifiers and radio power amplifiers. Audio power amplifiers, also called the small signal…
Metal Insulator Semiconductor Field Effect Transistors (MISFETs): The Metal Insulator Semiconductor Field Effect Transistors (MISFETs) is one of the most widely used electronic devices, particularly in digital circuits, because of…
Applications of FETs (Field Effect Transistors): Applications of FETs - FET has a very high input impedance (100 MΩ in case of JFETs and 104 to 109 MΩ in case of…
Crystal Oscillators - Circuit, Working, Advantages and Disadvantages: In crystal oscillators, the usual electrical resonant circuit is replaced by a mechanically vibrating crystal. The crystal (usually quartz) has a high…
What is Oscillator? - Types of Oscillators: An oscillator is the basic element of all ac signal sources and generates sinusoidal signals of known frequency and amplitude. It is one…
Facsimile (FAX) Machine - Definition, Operation and Applications: In addition to the basic signals consisting of speech, music, or telegraph codes, a telecommunications system is often required to transmit signals…
Difference between LED and Laser Diode: The Difference between LED and Laser Diode is given below: As already mentioned LASER is the shortened form of light amplification by stimulated emission…
Light Emitting Materials: Since the eye is only sensitive to light of energy hf ≥ 1.8 eV (~ 0.7 μm), semiconductors of interest must have energy band gaps larger than this…
