Abstract
A pass transistor signal level translator between a first voltage level and a higher second voltage level having a bias circuit for the pass transistor including a first switching circuit coupled to the first voltage level for providing a bias voltage that is less than the first voltage level. A second switching circuit is coupled to the second voltage level for providing a pulse at substantially the second voltage to the bias voltage. A voltage clamping circuit is coupled between the bias voltage and a reference voltage.
