Abstract:Scaling of CMOS technology causes the power supply voltages to fall and supply currents to rise at the same time as operating speeds are increasing. Falling supply voltages cause noise margins to decrease, while increasing current and frequency makes supply noise injection larger, especially noise caused by inductance in the supply lines. Creating power distribution systems is one of the key challenges in modern chip design. Decoupling capacitance helps reduce inductance effects, but there is often a peak in t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
