A method and apparatus for performing impedance profile control of a power delivery network (PDN) in an electronic device are provided. The method includes the steps of: utilizing a capacitive component and a resistive component that are coupled in series as an output stage of the PDN, wherein the capacitive component includes one terminal coupled to a first voltage level of the PDN and further includes another terminal, and the resistive component includes a first terminal coupled to the other terminal of the capacitive component and further includes a second terminal coupled to a second voltage level of the PDN; and inputting a control signal into a third terminal of the resistive component, to control an impedance profile of the output stage of the PDN, wherein in a predetermined state of the control signal, the control signal is a time variant signal. The control signal may be digital or analog.
