Abstract:
A passive component with temperature compensation and an electronic device using the same are provided. The electronic device includes a central processor unit (CPU), a filter and a power conversion circuit. The filter includes the passive component and a variable resistor. The passive component includes an inductor and a negative temperature coefficient (NTC) resistor. The NTC resistor is contacted with a surface of the inductor, and the NTC resistor and the inductor are disposed in a package. The power conversion circuit provides a current information to the CPU according to a partial voltage difference of the filter. The power conversion circuit controls an output voltage through the filter according to a first control signal of the CPU, so as to provide the output voltage. The electronic device further includes an embedded controller. The embedded controller controls the variable resistor according to a second control signal of the CPU.
