Contributor Vdovin, G. (mentor) Faculty Electrical Engineering, Mathematics and Computer Science Department Electrical Engineering Programme Electrical Engineering Date 2015-07-03 Abstract 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 insufficient refresh rates to support modern measurement systems. To aim for a higher resolution, the feasibility of applying audio DACs in the system is researched. To control the DACs, a hardware-based subsystem of the MCU receives USB data through DMA and interfaces with the DACs. Furthermore, a prototype is built and tested. This prototype is capable of updating the DAC outputs synchronously with a rate of 20 kHz.
