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
