Modern, large-scale analog integrated circuits (ICs) areessentially composed of metal-oxide semiconductor (MOS) transistorsand their interconnections. As technology scales down to deepsub-micron dimensions and supply voltage decreases to reduce powerconsumption, these complex analog circuits are even more dependenton the exact behavior of each transistor. High-performance analogcircuit design requires a very detailed model of the transistor,describing accurately its static and dynamic behaviors, its noiseand matching limitations and its temperature variations. Thecharge-based EKV (Enz-Krummenacher-Vittoz) MOS transistor model forIC design has been developed to provide a clear understanding ofthe device properties, without the use of complicated equations.All the static, dynamic, noise, non-quasi-static models arecompletely described in terms of the inversion charge at the sourceand at the drain taking advantage of the symmetry of the device.Thanks to its hierarchical structure, the model offers severalcoherent description levels, from basic hand calculation equationsto complete computer simulation model. It is also compact, with aminimum number of process-dependant device parameters.

Written by its developers, this book provides a comprehensivetreatment of the EKV charge-based model of the MOS transistor forthe design and simulation of low-power analog and RF ICs. Clearlysplit into three parts, the authors systematically examine:

• the basic long-channel intrinsic charge-based model, includingall the fundamental aspects of the EKV MOST model such as the basiclarge-signal static model, the noise model, and a discussion oftemperature effects and matching properties;
• the extended charge-based model, presenting importantinformation for understanding the operation of deep-submicrondevices;
• the high-frequency model, setting out a complete MOS transistormodel required for designing RF CMOS integrated circuits.

Practising engineers and circuit designers in the semiconductordevice and electronics systems industry will find this book avaluable guide to the modelling of MOS transistors for integratedcircuits. It is also a useful reference for advanced students inelectrical and computer engineering.
