Runaway Train

Runaway Train

This miniature choo-choo train was discovered rolling down the tracks on a LeCroy MVV 200 analog shift register integrated circuit. The existence of the train was brought to our attention by John T. Anderson of JPS Designs located in Elburn, Illinois. The "tracks" upon which the train is apparently riding are the high speed shift register. This chip is based on Charge Coupled Device (CCD) technology, where analog samples of electrical charge are temporarily stored in the chevron-shaped tracks, and control signals create electrical fields that "bump" the charge along from segment to segment.
