Ayman Fayed's research focuses on the design of integrated power-management circuits, especially DC-DC converters (voltage regulators that efficiently convert one DC voltage to another) used in mobile devices, microcontrollers, CPUs, and electric vehicles. Much of the work addresses improving efficiency, speed of response, and reducing electrical noise ('spurs') in these converters, including techniques like hysteretic control, multi-phase and multi-frequency converter designs, and current-sensing methods. Prospective students would likely work on analog/mixed-signal chip design problems related to power electronics and energy-efficient circuits.
Publication output has been steady over the last decade, averaging a few papers per year with a slight decline in the most recent two years.
