Amplifier Fundamentals
What are amplifiers?
In electronics, an amplifier is an electronic device or circuit which is used to increase the magnitude of the signal (a time-varying voltage or current) applied to its input, used chiefly in sound reproduction.
It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. Amplifiers have many properties include analog-to-digital conversion, common-mode voltage, negative feedback, single supply, frequency compensation, input offset voltage, open-loop, closed loop, finite gain, bandwidth, efficiency, temperature effects and so on. These amplifier properties can be important to take consideration depending on the applications. For example, a device consisting of an amplifier combined with a loudspeaker, used to amplify electric guitars and other musical instruments.
Amplifier Types
What are the different types of amplifiers?
There are a lot of different amplifier types, all with their own applications, characteristics and construction. This page lists the different amplifier classes which are described on the amplifier guide.
Whenever you are working on circuits containing amplifiers, they belong to discrete (built from individual transistors or tubes/valves), IC (fabricated in an Integrated circuit) — most common, and hybrid type depending on their constructions, such as operational amplifier, differential amplifier, power amplifier, distributed amplifiers, switched mode amplifiers, negative resistance amplifiers etc.
↪️Different types of amplifiers are listed here:
Active Devices
Power Amplifiers
Operational Amplifiers (op-amps)
Distributed Amplifiers
Switched Mode Amplifiers
Negative Resistance Amplifier
Amplifier Applications
Where are amplifiers used?
An electronic amplifier is a device that is used to increase the power, current, or voltage of a signal. Amplifiers are used in music equipment, electronic devices such as television and radio receivers, audio equipment, and computers to increase the amplitude of a signal.
Amplifiers can be used in a host of different circuits and applications. For example, as for operational amplifier applications, some of the more common applications are: as a voltage follower, selective inversion circuit, a current-to-voltage converter, active rectifier, integrator, a whole wide variety of filters, and a voltage comparator.
Amplifier Circuit Design
What is the purpose of amplifier circuit?
In electronic circuits, the purpose of an amplifier or an op amp is to amplify or increase the input signal to produce an output signal which is much larger than that of the input, with a similar waveform as that of the input.
The page can cover systems ranging from complex electronic systems all the way down to the individual amplifiers within an integrated circuit. Amplifiers are one of the main building blocks within electronic circuits, especially analogue circuits, where they provide an increase in the signal level. For example, amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds.
