1/28/2014   29 comments
Wearables are considered the next big thing in technology. However, how can you create more efficient, low-power devices that don't require a battery? It's a problem several universities are looking at under a new program called Assist.
Bring Back the Analog Computer
Derek Koonce  
1/27/2014   11 comments
Analog computers were popular and useful a long time ago. With the advent of digital computing technology, it may seem like analog computers are no longer useful to the designer. You may be surprised at the many areas that analog computing can provide an advantage over the newer and more powerful digital technology.
ADC Noise: How the Clock Input Can Help
Jonathan Harris  
1/24/2014   4 comments
One of the most critical areas on an ADC that can affect performance is clock noise. Good layout and routing techniques coupled with an optional filter can do wonders in improving key specs.
How to Bring New Life to Old Hybrid Circuits
Derek Koonce  
1/24/2014   20 comments
The challenge of recreating an old hybrid is two-fold. One, finding replacement parts for the old ones. Two, how to package for low quantity production.
