Claim:
1. A method comprising: determining a first capacitance value corresponding to a first set of load conditions associated with a power supply line in a user device; determining a second capacitance value corresponding to a second set of load conditions associated with the power supply line; detecting a first level of electromagnetic interference on the power supply line; determining that the first level of electromagnetic interference is above a threshold level; detecting occurrence of the first set of load conditions associated with the power supply line; setting, by a processing device, a tunable decoupling capacitor on the power supply line to the first capacitance value to reduce the first level of electromagnetic interference on the power supply line to a second level of electromagnetic interference lower than the first level; detecting a change from the first set of load conditions associated with the power supply line to the second set of load conditions; and setting, by the processing device, the tunable decoupling capacitor on the power supply line to the second capacitance value to reduce the first level of electromagnetic interference on the power supply line to a third level of electromagnetic interference lower than the first level.
