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

Scanning electron micrograph is shown alongside measured frequency characteristic for a 1.51GHz polydiamond micromechanical disk resonator. This is part of an atomic clock that takes up about a cubic centimeter.
An optical clock-injection chip micrograph. By replacing wires in chips with optical connections, researchers hope to cut power consumption and heat, the two major challenges facing semiconductor designers.
