Jump to Example amplifier circuit - Amplifier. An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device. This stereo amplifier circuit diagram is cheap and simple. It is probably the one of the easiest audio amplifiers to build. Let me show you. The power amplifier works on the basic principle of converting the DC power drawn from the power supply into an AC voltage signal delivered to the load. Although the amplification is high the efficiency of the conversion from the DC power supply input to the AC voltage signal output is usually poor.

Amplifier - Wikipedia

Check out the TEA datasheet for more information on basic amplifier circuit On the input side, you should use a dual potentiometer. A dual potmeter allows you to connect both left and right channel on one potentiometer.

This amplifier is great to use together with some speakers to get sound on your desktop computer. Amplification in practical applications is done using Multi-stage amplifiers.

A basic amplifier circuit of single-stage amplifiers are cascaded to form a Multi-stage amplifier. Let us see how a single-stage amplifier is built, which is the basic for a Multi-stage amplifier.

Single-stage Transistor Amplifier When only one transistor with associated circuitry is used for amplifying a weak signal, the circuit is known as single-stage amplifier.

Analyzing the working of a Single-stage amplifier circuit, makes us easy to basic amplifier circuit the formation and working of Multi-stage amplifier circuits.

A Single stage transistor amplifier has one transistor, bias circuit and other auxiliary components. The following circuit diagram shows how a single stage transistor amplifier looks like. When a basic amplifier circuit input signal is given to the base of the transistor as shown in the figure, a small amount of base current flows.

Due to the transistor action, a larger current flows in the collector of the transistor.

Basic Amplifier

In general the power amplifier is the last 'amplifier' or basic amplifier circuit circuit in a signal chain the output stage and is the amplifier stage that requires attention to power efficiency.

Efficiency considerations lead to the various classes of power amplifier based on the biasing of the output transistors or tubes: Audio power amplifiers are typically used to drive loudspeakers. They will often have two output channels and deliver equal power to each. An RF power amplifier is found in radio transmitter final stages.

A Servo motor controller: Operational amplifiers op-amps [ edit ] Main articles: Operational amplifier and Instrumentation amplifier An operational amplifier is an amplifier circuit which typically basic amplifier circuit very high open loop gain and differential inputs.

Op amps have become very widely used as standardized "gain blocks" in circuits due to their versatility; their gain, bandwidth and other characteristics can be controlled by feedback through an external circuit.

Though the term today commonly applies to integrated circuits, the original operational amplifier design used valves, and later designs used discrete transistor circuits. A fully differential amplifier is similar to the operational amplifier, but also has differential outputs.

Distributed amplifier These use balanced transmission lines to separate individual single stage amplifiers, the outputs of which are summed by the same transmission line.

The transmission line is a balanced type with the input at one end and on one side only of the balanced transmission line and the output at basic amplifier circuit opposite end is also the opposite side of the balanced transmission basic amplifier circuit.

Basic Amplifier

The gain of each stage adds linearly to the output rather than multiplies one on the other as in a cascade configuration. This allows a higher bandwidth to be achieved than could otherwise be realised even with the same gain basic amplifier circuit elements.

Switched mode amplifiers[ edit ] These nonlinear amplifiers have much higher efficiencies than linear amps, and are used where the power saving justifies the extra complexity.
