Claim Text:
1. A voltage regulator comprising: a first circuit to receive at least one feedback signal from a buck converter and to provide at least one driving signal to the buck converter to provide an output voltage based on the at least one feedback signal; and a second circuit to control a super-capacitor device to provide the output voltage from the super-capacitor device when the first circuit is not using the buck converter to provide the output voltage, wherein the super-capacitor device includes a first control transistor, a second control transistor and a super-capacitor in series, the second control transistor coupled in series between the first control transistor and the super-capacitor, and the second circuit to provide a first control signal to the first control transistor and to provide a second control signal to the second control transistor to control the output voltage from the super-capacitor device coupled in series to the first control transistor and the second control transistor.
