Abstract
A logic level shifter interface including a string of logic components communicating between a first power domain and a second power domain; a first string of resistive components connecting a first power rail of the first power domain to a first power rail of the second power domain and having a plurality of intermediate first power rails at nodes between adjacent resistive components of the first string of resistive components; and a second string of resistive components connecting a second power rail of the first power domain to a second power rail of the second power domain and having a plurality of intermediate second power rails at nodes between adjacent resistive components of the second string of resistive components, where at least one logic component is powered by an intermediate first power rail of the first string of resistive components and an intermediate second power rail of the second string of resistive components.
