CMOS Logic Circuits

• Definitions: IC, chip, microprocessor
• CMOS advantages
• Reminder of hierarchy

Transistors

• MOSFETS - n-channel, gate, drain, source
• Regions of operation: cutoff (OFF) and active (ON)
• Ideal switch model, voltage controlled
• p-channel MOSFET

Inverter Gate in CMOS

• n-FET, p-FET pair - complementary pair

Other Logic Gates in CMOS

• General structure
• Series and parallel connections
• NOR and NAND gates
