This lecture covers the historical evolution of CMOS technology from micro to nanoelectronics, described by Moore's law. It explains the structure and operation of MOSFET transistors, focusing on the DC and AC analysis. The lecture also discusses the characteristics of NMOS and PMOS transistors, the concept of threshold voltages, and the application of CMOS technology in digital and analog electronics. Additionally, it delves into the small-signal model of MOSFETs, transconductance, output conductance, and drain current analysis.
