GaN in Class-D Audio
Advantages with GaN Systems – A Comparative Look
The high performance of GaN Systems transistors in Class-D audio amplifiers is demonstrated in the GaN Systems Class-D Audio technical manual.
It is difficult to compare the GaN Systems’ results to the published efforts of Silicon MOSFET or other GaN-based solutions for a number of reasons. Among them are:
- Measurement Test Benches are not defined
- Measurement Conditions are optimized for a given measurement (and not specified)
- Test Platforms represent highly optimized versions of the Competitive amplifier design
- Test Measurements focus on the “best possible picture” parameters
- Special Test Measurements often reflect individual preferences
This whitepaper covers:
- Class-D Amplifier Transistor Approaches
- Device parameters and characteristics
- Performance
- Ease of Manufacturing
- Application Circuit Layout
