Noise in Amplifiers and its Types: Noise in Amplifiers - Noise is any kind of unwanted signal that is not related to the input. Any electronic component produces a certain…
Classification of Amplifiers: In the Classification of Amplifiers, the transistor amplifiers may be classified in several ways such as on the basis of transistor configuration used, active device used, output,…
Common Source JFET Amplifier with AC Equivalent Circuit: The Common Source JFET Amplifier Circuit configuration is the most widely employed configuration. It is because this configuration provides high input impedance,…
What is Dual Power Supply? -Circuit Diagram and its Workings? Many discrete and ICs need bipolar (dual power supply or ± V) supplies. This can be easily accomplished with two…
Regulated and Unregulated Power Supply: Almost all electronic devices used in electronic circuits need a dc source of power to operate. The source of dc power is used to establish…
Transistor as an Amplifier - Circuit Diagram and Its Workings: The main utility of a transistor lies in its ability of amplifying weak signals. The weak signal is applied at…
Maximum Power Transfer Theorem: Here, the maximum power transfer theorem has been discussed for resistive loads. The maximum power transfer theorem states that the maximum power is delivered from a…
Bridge Tied Load Amplifier: All of the power amplifiers already discussed have been single-ended (SE): meaning that they provide power to a load that has one terminal grounded and the…
