"MEMS: enables electrically trimmable passive resistor"

The inner workings of the world's first analog integrated circuit to incorporate electrically adjustable passive resistors will be described at the International Solid State Circuits Conference. ISSCC is being held Feb 3-8 in San Francisco. Microbridge Technologies Inc. will detail a trimmable Wheatstone bridge for piezoelectric sensors, made adjustable by virtue of its patented "rejustor" technology based on microelectromechanical systems.
