1. A level shifter, comprising:

  • a first transistor turned on by a control signal, for transmitting Vcc to a first node;

    a second transistor turned on by said control signal, for transmitting a zero voltage level to said first node;

    a third transistor turned on by said Vcc, for transmitting the voltage level of said first node to a second node;

    a fourth transistor turned by said zero voltage level, for transmitting the voltage level of said first node to a third node;

    a fifth transistor turned on by the voltage level of said second node, for transmitting a first voltage level to an output; and

    a sixth transistor turned on by the voltage level of said third node, for transmitting a second voltage level to said output.
