A method and structure for active power control of a power supply element coupled to an electronic circuit. The structure comprises a control element coupled to the electronic circuit, said control element comprising one or more of a phase detector, a counter, a level detector, a voltage controlled oscillator, and one or more transistive elements wherein the control element is operable to measure one or more oscillations of a power supply signal of the power supply element. The structure further comprises a stabilization element coupled to the control element and coupled to the circuit, comprising one or more capacitive elements, one or more transistive elements and one or more resistive elements, wherein said one or more capacitive elements, one or more transistive elements and one or more resistive elements are operable to mitigate one or more oscillations of the power supply signal of the power supply element. The determination of which capacitive elements and resistive elements to switch may be made by measuring the oscillations of the power supply signal, and reducing power supply oscillations by performing one or more of reducing amplitudes of corresponding resonance frequencies of the power supply signal, changing one or more characteristic frequencies of the circuit and injecting a feedback signal into a power supply of the circuit.
