  1. An Introduction TOVLSI EE 445Industrial electronicscourse presentation Ahmed Hamidaddin - 221836

  2. Introduction • A top down view of computer usage components: Manufactured practically using Program/App. Your Choice! High Level Language ICS 103 VLSI Assembly Language EE 390 Microprocessor EE 390 Digital Logic Blocks EE 200 Transistors (MOSFETs & BJTs) EE 203

  3. VLSI? • ICs are the basic block of electronic device design. • They contain many transistors on one chip. • Digital devices rely on digital logic. • First half of 20th century ruled by vacuum tubes. • The magical PN junction - 1939 • Transistor – 1947, BJT – 1949, TTL – 1962, • PMOS – 60’s, NMOS – 70’s, • CMOS – 80’s surviving until nowadays.

  4. Evolution • A logic block contains 2+ transistors. • You build your microprocessor using these blocks!

  5. Moore’s Law 1 Billion Transistors !!! K 1,000,000 100,000 Pentium® III 10,000 Pentium® II Pentium® Pro 1,000 Pentium® i486 i386 100 80286 8086 10 Source: Intel 1 1975 1980 1985 1990 1995 2000 2005 2010 Projected

  6. The PN Junction: The Secret Recipe!

  7. MOSFET Retrospect

  8. CMOS Inverter

  9. CMOS Inverter: Low Input I

  10. CMOS Inverter: Low Input

  11. CMOS Inverter: High Input 1 I

  12. CMOS Inverter: High Input 1

  13. CMOS NAND Gate

  14. CMOS NAND Gate

  15. CMOS NAND Gate

  16. CMOS NAND Gate

  17. Advantages of CMOS • Very low power consumption. • Rail-to-rail voltage. • Modular design. • Reliable and robust. Choice of the industry! Intel 4004 Intel Pentium 4

  18. One Main Challenge in CMOS • Increasing temperature increases gate leakage current, or the current escaping through the gate oxide.

  19. Design Hierarchy SYSTEM MODULE + GATE CIRCUIT DEVICE G D S n+ n+

  20. Design Flowchart System Requirements Logic Design VLSI Design and Layout fail Design Verification pass Fabrication/Synthesis

  21. Conclusion • VLSI is a mature field of electrical and computer engineering that deals with semi-conductor properties to design patterns that form the building blocks to serve digital circuit design purposes. • BiCMOS, ECL, TTL technologies currently used. Each has its own applications for its advantages. • Serious VLSI research, design and cutting-edge manufacturing takes place in extremely sophisticated factories and labs (fabs).
