The design of analog integrated circuits is complex because it involves several aspects of device modeling, computational methodologies, and human experience. Nowadays, the well-stablished CMOS (Complementary Metal-Oxide-Semiconductor) technology is mandatory in most of the integrated circuits. The basic devices are MOS transistors, whose manufacturing process is well understood and constantly updated in the design of small devices. Detailed knowledge of the devices technology is needed for modeling all aspects of analog design, since there is a strong dependency between the circuit behavior and the manufacturing process. |
