Abstract
Power amplifier circuit for integrated digital circuits that combines the low permanent current consumption of a NOF push-pull output stage with the well-defined high level of a NON-NOFF amplifier stage having external clamp diode. An optimization of the leading edge is additionally achieved by fast drive and transient overdrive. A preceding inverter reduces the input capacitance of the overall circuit.
