Abstract
An electronic devicehas circuitrywhich operates in a first voltage domainsupplied with a first voltage level VDDand a reference voltage level. A voltage regulatorgenerates the first voltage level VDDfrom a second voltage level VDDhigher than the first voltage level VDD. At least one power gateis provided for selectively coupling the circuitryto one of the first voltage level VDDor the reference level. The control signalfor the power gateis generated in a second voltage domain supplied with a higher voltage level VDDor VDDderived from the second voltage level VDDsupplied to the voltage regulator. Hence, an existing high voltage source within the devicecan be reused for applying a boosted voltage to power gates to improve efficiency of power gating.
