Abstract:
1. A method of making a level shifter comprising: coupling a driver stage between an input end and an output end, the driver stage comprising a first transistor and a second transistor; coupling an inverter with the input end, the inverter having an input and an output; coupling a third transistor with an output of the inverter, the third transistor having a terminal and a gate end, the terminal of the third transistor being coupled to a pumped voltage (VPP); coupling a fourth transistor with the output end, the fourth transistor having a terminal, the terminal of the fourth transistor being coupled to the pumped voltage; coupling a fifth transistor with the input end, the fifth transistor having a terminal, the terminal of the fifth transistor being coupled to the third and fourth transistors; and coupling a sixth transistor with the input end, the sixth transistor having a terminal.
