Backwards to the future? Power DesignLine Blog 1/24/2005 Post a comment Dr. Frank says that it is inevitable that designs will run out of materials improvements that can be cost-effectively integrated into the manufacturing process, which means we will run out of ways to keep logic voltages from decreasing in proportion to device size. This has some strange implications such as the smallest transistors may not be the most power efficient. What to do?
