Abstract
A level shifter in a primary voltage domain has a control module receiving an input signal from a secondary voltage domain for controlling operation of the level shifter. The control module includes a complementary pair of transistors and a first native transistor connected in a series current conduction path in the primary voltage domain. The complementary pair of transistors have gates connected to receive the input signal and the first native transistor has a gate connected to limit to a leakage current the current in the series current conduction path.
