CMOS technology and circuits
Logic circuit design

Since CMOS technology has become the dominant integrated circuit technology since the 1980s, we begin by presenting its essential characteristics. They will enable us to :

• show how inverters, NAND gates, NOR gates and some gates implementing more complex logic functions can be realized by modeling the operation of MOS transistors as switches;

• explain the problems, particularly in terms of power dissipation and energy consumption, encountered in state-of-the-art CMOS technologies.
