High-speed GaN FET driver switches at 40 MHz
Audio systems are challenged to both minimize size and deliver exceptional audio quality to listeners. At the system-design level, better audio performance and sound quality occur when distortion is reduced. MOSFET components have parasitic diodes and gate capacitance that creates jitter and distortion in class-D audio systems, whereas GaN FETs have much smaller gate capacitance […]
