Special Issue Information
Deae Colleagues,
GaN devices and applications constitute viable technologies but have also undergone a process of being productized in over the past decade. The superior qualities of GaN technology include high efficiency, fast switching speed, dense physical size, and high tolerance to very high- and low-temperature operations. GaN technology is not only gaining traction in power and RF electronics but is also rapidly expanding into other applications such as radar, space, digital and quantum computing electronics. In power electronics, GaN devices are greatly desirable for use to explore both higher-voltage and ultra-low-voltage power applications. Moving into the RF and audio engineering domains, GaN devices have uses in the implementation of AI-assisted and digitized power amplifier circuits, and further advances are expected using the hardware–software co-design approach. There are also increasing needs for higher integration technology of GaN devices and of other technology like silicon. High-performance p-type GaN technology will be crucial to the realization of high-performance GaN CMOS circuits. Finally, given the increasing cost of hardware prototyping of new devices and circuits, the use of high-fidelity device models and AI- and data-driven modeling approaches for technology-circuit co-design are projected to be the design trends of the future.
This Special Issue is aimed at addressing some of the above challenges. This includes but not limited to:
- Next-generation GaN device architecture with or without new material;
