  1. EDA (Circuits) Overview Paul Hasler

  2. Extent of Circuits (Analog/Digital) Hearing aids Cell Phones Digital Cameras Automotive MEMs devices / Circuits Biomedical Analog ~ 20% of IC market since 1970

  3. “The Analog Renaissance is Here!” --- Brian Halla CEO National Semiconductor “Analog chips enable computers to interact with the physical world--to see, listen, touch. . .the next ten years will see a shift in emphasis to analog technologies. . . In the coming years, look for analog--not digital--chips to attract the new talent and investment. . .” --- Red Herring Magazine, February 2003 "DSP and high-performance analog are the engines . . . and we're only at the beginning of where analog is going." --- Templeton, incoming CEO of TI, February 2004

  4. Range of Analog Products (Just TI’s map)

  5. Brief History of Integrated Circuits (1960) 4004: First mP (1970)

  6. Silicon Scaling “Standard” digital CMOS

  8. ECE 4430: Analog IC Design

  9. Sensor Signals Real world (analog) A/D Converter DSP Processor Computer (digital) ASP IC Specialized A/D DSP/mC Real world (analog) ASP IC Computer (digital) DSP Processor A/D Analog--Digital Signal Processing Gene’s Law and CADSP CADSP = Cooperative Analog—Digital Signal Processing (P. Hasler and D. Anderson) Gene’s Law = power efficiency scaling for DSP mC Power and Computation Efficiency Critical for Mobile Applications Custom Analog ~ 10,000 more efficient than Custom Digital • Standard CMOS process • Greater signal processing capability without scaling IC process

  10. Physical Layout Cross-section Schematic m m x n n Programmable Analog Circuits Programmable Analog Structure: • Core Innovation - Charge storage and control in signal path - Combine to build computational engines - Any standard CMOS process Implementation: • Analog Parameter Storage - CMOS offset correction, Yield enhancement - Analog data storage • Programmable Analog Functions - Amplifier gain, Filter parameters - Reconfigurable analog circuits • Dynamic Analog Computation - Matrix multiplication, Linear transforms - Adaptive Analog Systems Example Functions

  11. Field Programmable Analog Array (FPAA) • Configurable Analog Block (CAB) • Synthesizes analog functions • Fully programmable functions, not just selectable • More efficient than selectable • Base block for FPAA FPAA (36 CAB, 150k Elements)
