## Summary

Jørgen Jakobsen, an IC designer at Mios Audio, details his career designing hearing aid chips in Denmark and his current work on ultra-low-power Class D amplifiers. He explains how Mios Audio's multi-level output stages eliminate idle losses, achieving ten times lower power consumption at normal listening levels compared to traditional Class D designs. The conversation covers the technical challenges of integrating RF, DSP, and analog audio on small silicon areas, as well as the use of open-source platforms like the ESP32 for prototyping these high-efficiency audio solutions.
