How a Humble Circuit Designer Revolutionized MOS Transistor Modeling

CMOS circuit design is based on two fundamental pillars: Understanding how MOS transistors operate, so a designer can innovate new circuit topologies and functions or know how to adjust the geometry and bias of transistors in existing circuits to meet performance goals; and understanding how accurate the MOS transistor models used in circuit simulators are, to know where the results of the detailed simulations used to verify circuit performance can or cannot be trusted.
