Balancing Efficiency, EMI, and Application Cost in Class-D Audio Amplifiers

  • Chapter
  • First Online:
Low-Power Analog Techniques, Sensors for Mobile Devices, and Energy Efficient Amplifiers

Abstract

Class-D amplifiers typically require more external components than class-AB amplifiers to achieve high efficiency and keep electromagnetic interference (EMI) under control. In this chapter, an overview is given of innovative class-D architectures and how they balance efficiency, EMI, and application cost.
