This text investigates the fundamental physical operation and mathematical modeling of the metal-oxide-semiconductor (MOS) transistor. Authored by Yannis Tsividis, a distinguished professor of electrical engineering, the book synthesizes semiconductor physics with circuit-level modeling. It provides a rigorous framework for understanding how these devices function within modern microelectronic systems, bridging the gap between device-level physics and integrated circuit design.

Experts and academics widely recognize this work as a foundational text for students and professionals in microelectronics. Readers frequently note the technical density of the prose, which requires a strong background in solid-state physics and circuit analysis to fully grasp.
