Class G Headphones Amplifier

Today s portable devices present many challenges ranging from output power to maintaining high levels of efficiency. As devices continue to become more feature rich, consumers will continue to demand higher levels of performance along with minimal battery power consumption, putting further emphasis on proper design of key components such as the headphone amplifiers. Headphone amplifiers are migrating from Class AB to Class G technology. The differences and design advantages of each technology will be addressed in this work.
