Abstract

A means will be illustrated wherein a separate power connection is employed for control based inversion on pass-gate circuits that eliminate the need for levels translators when said pass-gate circuits are connected to a low power supply, Vddl, and any of the data inputs are driven from circuits connected to a higher power supply, Vddh. This approach will reduce the number of levels translators needed in a voltage island based design and lower the overall power while improving performance.
