Abstract
An inductive electronic identification device and a power-supply-compensation circuit of the same are provided. The power-supply-compensation circuit has a power supply unit and a compensation circuit, and connects to a load unit for supplying the load unit to operate. The compensation circuit receives the compensation signal from the load unit, so that the voltage regulator of the compensation circuit controls the voltage rise and fall of one end of the capacitor of the compensation circuit. The capacitive element switches to the charging or discharging mode according to the power consumption of the load unit. In this way, electrical charges are stored when the load unit consumes less power, and compensation current is provided when the load unit consumes more power, so as to maintain the normal operation of the load unit.
