摘要：
A voltage level shifter is provided. The voltage level shifter includes an input stage and at least one level shifting stage. The input stage receives an input voltage and a complementary input voltage and receives a first supply voltage and a ground voltage. The input stage outputs one of the first supply voltage and the ground voltage over a first output voltage node and a first complementary output voltage node based on the input voltage and the complementary input voltage. A level shifting stage is coupled to the input stage. The level shifting stage receives the first supply voltage and a second supply voltage and outputs one of the ground voltage, the first supply voltage and the second supply voltage over second and third output voltage nodes and second and third complementary output voltage nodes based on voltages of the first output voltage node and the first complementary output voltage node.
