Photos: Chips, clocks, cells...oh my!

At the 2005 IEEE International Solid-State Circuits Conference this week, scientists took on topics from mini atomic clocks to the latest in small-jitter DLLs.

    Small devices such as this double gyroscope mounted in a 44-pin metal case could allow companies to add navigation capabilities to a wide variety of products. The gyroscope was shown at the IEEE International Solid-State Circuits Conference this week in San Francisco.

    A nerve cell from a rat is pictured on an array of transistors. An electronic current inside the cell can cause a change in the electronic state of the chip, and vice versa. Biological silicon interfaces like this could become an initial step toward brain-computer hybrids.
