Abstract
A driving circuit to drive an output stage comprising a high side NMOS and a low side NMOS is provided. The driving circuit comprises: a diode comprising an anode and a cathode, wherein the anode is electrically connected to a first voltage source and the sources of a first and a second PMOS; a third and a fourth PMOS both comprising a drain, a source and a gate, wherein the sources are respectively connected to the gates of the second and first PMOS, the drains are respectively connected to the drains of the first and second PMOS. A first and a second NMOS both comprise a drain, a source and a gate, wherein the drains are respectively connected to the drain of the fourth and third PMOS, the sources are coupled to a second voltage source, the gates are respectively connected to a first input and a second input.
