Abstract
The invention provides for maintaining a charged node point at the potential level of a power source, when the potential must be dynamically sustained. This is done by a circuit using insulated-gate, field-effect transistors. Preferably, two such transistors are used in conjunction with a bootstrap capacitor which changes the potential of a signal appearing at a circuit node responsive to any leaking of current at an output, which might otherwise cause the node potential to drift down to a lower level.
