ABSTRACT:
The present invention relates to a power output stage for the control of plasma screen cells. It includes VDMOS-type N-channel charge and discharge transistors, the charge transistor being arranged to form a compound P-channel transistor. These transistors enable to issue a charge current to an output and to absorb a discharge current from this output. Two inverters are sized so that the potential of the control gate of the charge transistor drops more rapidly than the output potential when a discharge of this output is controlled. Thus, an output stage of limited bulk and without any risk of simultaneous conduction of the charge and discharge transistors is implemented.
