Design of a 60W MOS Power Amplifier

The power amplifiers in a sound system will be responsible for increasing the input to a certain level at which the speaker can play audio in a space with adequate sound pressure. When these spaces are wide, it takes a lot of pressure and this requires a high power, which should be given to the speaker without causing a variation in the pattern of the input signal. To achieve this goal is mainly used this concept: a suitable configuration, also called topology. The audio power amplifiers are mostly being built under the AB topology, achieving maximum theoretical efficiency of 78.5%. This paper presents an analysis of an MOS power amplifier designed under this topology, showing characteristics, quality measures and indices, resulting in an efficient audio amplifier. This work was realized as open ended problem project.
