    摘要： A dynamic current supply is connected between the emitter electrode of an output transistor and a point of reference potential, to progressively increase the magnitude of the flow of current therebetween, as the output signal at the emitter electrode approaches the point of reference potential. The dynamic current supply includes a current mirror, the output of which is in the path of and controls the flow of current. An MOS transistor, the conductivity of which is a function of the difference in potential between the operating voltage supplied to the output transistor and the output signal, supplies the input or control current to the current mirror.

    摘要： A voltage buffer for capacitive loads isolates the load from the feedback loop. Using a variation of a follower arrangement, a second transistor outside of the feedback loop introduced. The current to the load is supplied through the second transistor, which is connected to have the same control gate level as the transistor in the feedback loop and provide an output voltage based on the reference input voltage. The output voltage is dependent upon the input voltage, but the load is removed from the feedback loop. By removing the load from the feedback loop, the loop is stabilized with only a very small or no compensating capacitor, allowing the quiescent current of the buffer to be reduced and the settling time to be improved. One preferred use of the present invention is to drive the data storage elements of a non-volatile memory.

    摘要： An amplifier system includes a constant current unit which produces a constant current in response to a source voltage from a source voltage terminal. An emitter follower unit has a base, an emitter and a collector, an input signal being supplied to the base, the emitter being connected to the constant current unit, the source voltage being supplied to the collector, the emitter follower unit producing an output signal at the emitter in response to the input signal. A current regulating unit regulates the constant current in response to a collector current fed into the collector of the emitter follower unit, so that the constant current is fed from the emitter of the emitter follower unit into the constant current unit.
