Abstract
A processing device detects an occurrence of the first set of use conditions associated with a power supply line coupled between a power source and a power sink in a user device. The processing device sets a tunable decoupling capacitor on the power supply line to a first capacitance value to reduce a level of electromagnetic interference on the power supply line at a first frequency corresponding to the first capacitance value. When the processing device detects a change from the first set of use conditions associated with the power supply line to a second set of use conditions, the processing device sets the tunable decoupling capacitor to a second capacitance value to reduce a level of electromagnetic interference on the power supply line at a second frequency corresponding to the second capacitance value.
