Abstract
Each half of a differential-input amplifier stage has an input terminal connected to the emitter electrode of a transistor. Resistances are provided for sensing the flow of current through the principal conduction path of each transistor. Output signal current for the stage is taken from the collector of at least one of the transistors and applied to the input of a following one of a cascade connection of amplifier stages. Voltage comparator means sense the drop in potential across one of the resistances caused by reduction of current in one half of the diffferential-input amplifier to increase the current available to the other half. This increases the output signal current available to charge or to discharge capacitance in the stage(s) cascaded after the diffferential-input amplifier, increasing the slew rate of the cascade.
