Kirt's Cogitations™ #21
"Factoids," "Kirt's Cogitations," and
"Tech Topics Smorgasbord"

A Cool Concept
If the people at Research Triangle Institute have their way, you might just be able to have your cake and eat it too, at least when it comes to keeping ICs cool. A prototype semiconductor thermoelectric device has been developed that is many times more efficient at cooling that anything that has preceded it. Their array cools a small block of steel by 15 °F in 2 minutes. It works in reverse, too; that is to say it generates electric current when exposed to heat. Imagine mating this device to a cell phone PA and having it boost efficiency by both keeping it cool and feeding the heat-generated current back to the bias circuits. Visions of grandeur by the inventors foretell of the eventual replacement of conventional refrigerators and air conditioners. No time line has been proposed, however.

About RF Cafe RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived... |
