  3. Course outline • Introduction to CMOS circuits • MOS transistor theory • Circuit Characterization • Performance evaluation & optimization • CMOS circuit logic and design • Subsystem design • Datapath design and analysis

  4. Grading structure • Homework: 10% • Midterm: 25% • Lab Assignments: 20% • Term project: 20% • Final: 25%

  5. Solid State Devices • Silicon • Doping • n-type, p-type silicon • Carriers • electrons and holes • P-N junctions • 2 terminal devices • Transistors • Bipolar Junction Transistors (BJT) • Metal Oxide Semiconductor (MOS) • 4 terminal devices • Main emphasis of this class

  6. Integrated circuits • nMOS and pMOS devices • Modeled as on-off switches • But a lot goes on inside! • Complementary MOS (CMOS) circuit design methodology • Most common and widely used technique • But several other interesting techniques exist

  7. Moore’s Law Courtesy: Intel, http://www.intel.com/technology/mooreslaw/

  8. Moore’s Law continued.. • Number of components in an integrated circuit double every 2 years • Signifies increase in computing capacity, memory and speed exponentially

  9. MOS structure • n-channel • p-channel

  10. Technology nodes • Scaling • 0.25um,0.18um,90nm,65nm,45nm,32nm… • Pitch • Gate length • Device sizes • Frequencies

  11. Current Computing Capabilities • Intel’s 80-core processor: ~Terra flops • Over a billion transistors per chip • 4-5 GHz chip clock

  12. Issues and challenges of VLSI today • High Power dissipation • Faster operation • Methodologies to address these issues

  13. Looking ahead • CMOS technology • Stable and well understood process • Future technologies • Nanodevices • Molecular devices • Single electron devices • Quantum dots • Many more… • The future is basically yours to invent!
