An overview is presented of recent developments in the analog boundaries of the audio chain. The main focus is on class-D amplifiers that are by now almost standard in consumer applications and emerging in automotive and mobile applications as well. Further, an overview of the state-of-the-art in A/D and D/A conversion is given.
