High Performance Digital-input Class-D Amplifier

Class-D amplifiers have gained popularity for their high-power efficiency, exceeding 90%. Among them, digital-input Class-D amplifiers stand out due to their superior integration and increased immunity to electromagnetic interference (EMI). This project introduces a high-performance digital-input Class-D amplifier, aiming for a dynamic range...

A High-Speed 40-channel USB 3.0 DAC for Adaptive Optics

A High-Speed Digital-to-Analog converter system is proposed that is controlled using USB 3.0. Possibilities to improve the refresh rate and resolution are researched to meet the standards of modern measurement systems. For instance, adaptive optics often uses a DAC in its feedback loop, but the USB DAC systems currently available provide...
