Abstract
A voltage level shifting device includes an activation or deactivation control input, first and second output nodes, a capacitor coupled between the output nodes, a high-voltage transistor for charging the capacitor, a high-voltage transistor for discharging the capacitor, a comparator which generates a charge blocking signal and a discharge signal, and a control device which is operative to cause the charging transistor to be blocked when a charge blocking signal is generated and to turn on the discharging transistor upon receipt of a deactivation control signal and when a discharge signal is generated.
