GaN Power ICs: Reviewing Strengths, Gaps, and Future Directions

This paper reviews monolithic GaN integration for power ICs, focusing on current technological capabilities. We highlight key opportunities for integrating low-voltage circuits alongside power devices to support converter operation. Simulations and experimental results from the imec 200 V GaN-on-SOI and ON Semiconductor 650 V GaN-on-Si processes provide quantitative insights for digital and analog circuitry.
