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
