Abstract: The class D amplifier is well known in audio applications since a few ten years. The MOS transistors switching power stage is able to drive a useful power up to 500W to the loud speaker with an excellent power ratio (greater than 90%). Designing such an amplifier is obviously more difficult than designing a classical class A or AB power amplifier. Unfortunately, only mathematical and very complex theoretical approaches are found in the scientific literature. So, we present here a simple and concrete method for students and young designers to design a sigma delta class D amplifier as easily as possible. The experimental results are given to illustrate the design method. Finally, we explain how we exported this work towards pedagogical application and practical lessons for our engineer students.
