Abstract :
The purpose of this work is to explore how device operation parameters such as switching speed and power dissipation scale with voltage and temperature. We simulated a CMOS ring oscillator under different stress conditions to determine the accurate scaling relations of these operating parameters. Reduced voltage, frequency and temperature applied to a device will reduce its internal stresses, leading to an improvement of device reliability. Since all these variations for a single device are proportional, the ratios can be applied to a full circuit and help to simplify the derating model and formulate practical design guidelines for system developers to derate devices for long life applications.
