Abstract
A surge current compensating circuit has a compensating current generation unit, a bias unit, and a switch unit, for compensating a surge current drawn from a supply power after an output signal of a specific circuit transits. The compensating current generation unit is electrically coupled to the output stage of the specific circuit. The bias unit is electrically coupled to the compensating current generation unit through the switch unit. Before the output signal transits, the switch unit is disabled and the compensating current generation unit is enabled, so as to draw the compensating current from the supply power. After the output signal transits, the switch unit is enabled and the compensating current generation unit is disabled, such that the compensating current is not drawn from the supply power.
