ABSTRACT:
A buffer circuit has first and second boot-strap circuits. The first boot-strap circuit charges the gate of an output MOS transistor to a voltage above a supply voltage when an input signal has a first logic level. The gate of a precharging MOS transistor in the first boot-strap circuit is driven by the second boot-strap circuit so as to precharge a capacitor in the first boot-strap circuit to a voltage above the supply voltage when the input signal has a second logic level.
