The term amplifier refers to any device that increases the amplitude of a signal, usually measured in voltage or current. This versatile device is used in a variety of different electronic applications. Especially in audio technology, a wide range of amplifiers can be produced based on product specifications (i.e. power, voltage, current). Currently, there are many types of audio amplifiers available for consumers. Sound signal amplification is used for instruments, such as the guitar or the bass. They are also used commonly in home theater systems and with stereo speakers. The basic design behind all of these amplifiers is derived from the simplest concepts of circuit design.
For our project, we set out to design an audio amplifier. The inputs of our circuit were stereo signals from a portable music player. Although we used a low-power speaker, we needed to achieve approximately three times gain over the entire circuit. In addition, the amplifier had to be produced at a low cost with available materials. Before building the actual amplifier, we realized that we had to design, simulate, and test the circuit. Each step was necessary to understand the concepts involved in amplification
