Using "Empty Space" for IC Congestion Relief
News & Analysis  
6/26/2003   Post a comment
In past technologies, the ratio between device size and minimum wire width and spacing was large enough to reserve enough routing resources, so the fixed-die approach yielded nearly 100% utilization. However, in today's deep submicron technologies, shrinking device size no longer reserves enough wire tracks to complete the routing. Hence, wire area has become a major factor in completing a design. It is not uncommon that more than half of the modern chip is occupied by "white space" or "in

Serial 8-bit data programs digital pot for logarithmic control
News & Analysis  
6/25/2003   Post a comment
The Winbond WMS720x series is a family of 256 linear step, software controlled digital potentiometers. Some applications require logarithmic steps however, for example an audio volume control. The relatively large number of steps available in the WMS720x series allows us to use software to approximate logarithmic operation in that kind of application. This feature will investigate how this may be done, present a solution and will analyze the step accuracy inherent in the application.
