Augmented reality (AR) and virtual reality (VR) are rapidly transforming our lives by providing realistic, interactive experiences enhancing medical training, education, and entertainment. This project develops compact, energy-efficient class-D audio amplifiers with high audio fidelity to enhance user experience and battery lifetime in these devices. The project pushes innovation in microelectronics and strengthens the Netherlands' position in advanced semiconductor technology.
LOCAR: Low-power Class-D audio amplifiers for Augmented and Virtual Reality
This project addresses the growing demand for compact, energy-efficient, high-fidelity audio amplifiers in augmented and virtual reality (AR/VR) devices. In this TKI HTSM-funded initiative, TU Delft and Silicon Integrated BV develop innovative class-D amplifiers tailored for smart glasses and wearables, combining low power consumption with premium sound quality. The key innovation is a new system-level architecture, which will be validated by behavioral model, simulations and prototype measurements. This research supports emerging AR/VR markets and portable audio solutions, advances microelectronics design, and strengthens the Netherlands' leadership in semiconductor technology.
