Abstract
An overdrive circuit includes a pull-up circuit and a pull-down circuit. The pull-down circuit includes first, second and third transistors electrically connected in cascode between an output node and a low voltage supply node. A capacitor is electrically connected from a gate electrode of the third transistor to a gate electrode of the first transistor. A first mono-directional bias device is electrically connected from a drain electrode of the first transistor to a gate electrode of the first transistor. A second mono-directional bias device is electrically connected from the gate electrode of the first transistor to a source electrode of the first transistor.
