Abstract
The invention can utilize a switching power regulator and a non-switching power regulator in conjunction to provide regulated power to the digital logic. The digital logic and switching regulator may be deactivated during RF activity so that interference from both the digital circuitry and the switching regulator is significantly reduced. The state of the digital circuitry may be maintained during this standby period by using the non-switching power regulator to provide an as- required leakage current to the digital circuitry in order to maintain state. After the RF event (e.g. sending or receiving data) has concluded, the switching regulator may be activated and digital processing continued using the digital logic with no loss of continuity.
