Abstract
The invention relates to an electronic level shifter circuit for driving a high-voltage output stage. This output stage comprises a complementary pair of transistors connected between first and second supply voltage references, and at least one PMOS pull-up transistor connected in series with an NMOS pull-down transistor. An additional transistor is connected in parallel with the pull-up transistor, and the driver circuit has a first output connected to the control terminal of the pull-up transistor and a second output connected to the control terminal of the additional transistor.
