Summary: | A circuit for neutralizing very fast current fluctuations in a power consumer circuit, such as an integrated circuit having a pair of input or output conductors includes a bipolar transistor 17 whose collector is connected via a parallel connection of a semiconductor diode and a resistor to one of the conductors. The emitter of the transistor is grounded and the base is connected to the other conductor. Another parallel connection of a diode and a resistor is connected between the two conductors to bias the transistor to a preset current when a standard current of a constant magnitude flows through the consumer circuit. If current surges or breaks occur in the standard current, the preset current flowing through the collector resistor undergoes corresponding changes and a compensating current is very fast loaded to the conductors through the capacitance of the barrier layer of the p-n junction of the collector diode to neutralize the changes of the standard current. |
