This document discusses the growing importance and applications of analog circuits and technologies. It notes that while digital circuits currently dominate the integrated circuit market, analog circuits enable interaction with the physical world through sensing and actuation. The document highlights that analog circuits are expected to attract more talent and investment in the coming years. It provides an overview of analog product areas at Texas Instruments and discusses directions for education in analog and mixed-signal circuit design. Programmable analog circuits that can dynamically configure analog functions are also described as enabling more efficient computation for applications like sensor signal processing.

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
