Abstract
A level shifter with cross coupled inverters having different threshold voltages. The output of the level shifter is pulled to a known voltage state during power up. In some examples, one of the inverters includes an additional N-channel transistor wherein the threshold voltage is greater the threshold voltage of the other inverter due to the additional transistor.
