A few engineers were having a debate. According to all the books, some of them said, op amps are supposed to have zero output impedance, or very low. That means the output voltage wonâ??t change, just in case the output current changes. Some older op amps had an output impedance of 600 ? or 50 ?. So, the gain of the amplifier wonâ??t change just because the load changes. That must be good. But a couple of other engineers pointed out that many modern op...... Read the Entire Post Here
At the 2008 International CES, there are some “press only” events, one of which is called Showstoppers. This event brings together more than 100 vendors in one venue, each showing off their offerings. Usually, I make appointments to see people at this event, but I also roam the floor looking for interesting new products.

My wife had been nagging me to connect her notebook computer, which she works at in the kitchen, to one of our printers in the basement. Although this is the notebook issued to...Read the Entire Post Here
In a sort of American Idol for the mobile technology world, the GSM Association held its American leg of the 2009 Mobile Innovation Global Award Competition in Atlanta on June 3-4. This was a cool event bringing together top innovators and thought leaders in the mobile market space, and I enjoyed the chance to see so many new technologies on one stage. ...Read the Entire Post Here
