Audio - ClassD: Class D Amplifiers: Fundamentals of Operation

http://audio-classd.blogspot.com/2010/10/class-d-amplifiers-fundamentals-of.html

Saturday, October 30, 2010. Class D Amplifiers: Fundamentals of Operation. In the past, the power-efficiency advantage of classical PWM-based Class D amplifiers has been overshadowed by external filter component cost, EMI/EMC compliance, and poor THD N performance when compared to linear amplifiers. However, most current-generation Class D amplifiers utilize advanced modulation and feedback techniques to mitigate these issues. The Basics of Class D Amplifiers. In mathematical terms, this means that:.
