Voltage stabilizer stabilizing the voltage of a power line wherein power consumption elements are individually activated based on a quantity of currents to be drained

摘要

A digital circuit unit includes at least one circuit block, a voltage source for supplying the circuit block, a detection unit, which monitors the change of current drain by the at least one circuit block, an additional power consumption unit, which upon activation consumes power in addition to the at least one circuit block, and a control unit, which controls the power consumption unit in such a way that upon a change in the power consumption of the circuit block the power consumption unit is activated and drains current.
