CMOS Gates and Logic Systems

This lecture covers the basics of Complementary Metal Oxide Silicon (CMOS) gates and Logic Systems, focusing on the operation and characteristics of Metal Oxide Silicon Field Effect Transistors (MOSFETs) compared to Bipolar Junction Transistors (BJTs). It discusses the differences in operation, complementary functions, and advantages of CMOS over Transistor-Transistor Logic (TTL) gates. The lecture also explores the impact of gate charge, energy consumption, and voltage tolerance in TTL and CMOS circuits, highlighting the trade-offs between speed, energy efficiency, and robustness. Additionally, it addresses interfacing challenges between TTL and CMOS technologies, emphasizing the need for proper signal level adaptation to ensure seamless communication between different logic families.
