Abstract
A circuitry comprises an amplifier with a bipolar transistor, whose base terminal is coupled to an input terminal for a signal to be amplified. A biasing means for setting a potential at the base terminal of the bipolar transistor is provided. Further, a means for providing such a current to the base terminal of the bipolar transistor is provided, so that a charging or discharging current to the input terminal is larger than a base current of the bipolar transistor. Further, the circuitry comprises a means for detecting whether a potential change at the base terminal of the bipolar transistor is to be effected for switching the bipolar transistor, and a means for connecting the means for providing the current to the base of the bipolar transistor when a potential change is to be effected at the base terminal of the bipolar transistor.
