Abstract
A pre-driver includes first, second, third, and fourth P-channel field effect transistors (PFETs) with voltage ratings equal to a low first voltage (V). Between power rails at Vand at a higher second voltage (V), the first and third PFETs are series-connected and the second and fourth PFETs are also series-connected. The third and fourth PFETs are cross-coupled. The first and second PFETs have gates that receive a pre-driver input signal (Pin) that switches between Vand ground and an inverted pre-driver input signal (Pinb), respectively. At an output node between the first and third PFETs, the pre-driver outputs a driver input signal (Din) that switches between Vand V. A circuit includes this pre-driver (e.g., connected between a voltage level shifter and a driver or connected between a voltage level shifter and a buffer).
