Low power, process independent, full transistor controlled slew rate, PCI compliant I/O pads

Self-adaptable slew rate control output buffer for embedded microcontroller port applications

“…Process variations are detected by comparing an external reference voltage against the voltage drop of the drivers under certain loading conditions [5]. Compared to other possible designs that make use of passive elements, [6] greatly simplifies technology migration and turns out to minimize power consumption. The authors in [6] have described a method for transistor sizing and found an acceptable solution for several 3.3V Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.…”
