Abstract
An improved level shifter is disclosed. The level shifter is able to achieve a switching time below 1 ns using a relatively low voltage for VDDL, such as 0.75 V. The improved level shifter comprises a coupling stage and a level-switching stage. A related method of level shifting is also disclosed.
