Abstract:
1. A voltage regulator configured to receive a first voltage signal and provide a final voltage signal based, at least in part, on the first voltage signal, the voltage regulator comprising: a flying switched-inductor regulator having a first input terminal configured to receive a first voltage signal, a second input terminal configured to receive a second voltage signal, and an output terminal configured to provide an intermediate voltage signal based, at least in part, on the first voltage signal and the second voltage signal; a step-down regulator comprising an input terminal, coupled to the output terminal of the flying switched-inductor regulator, an output terminal, and a plurality of capacitors, wherein the step-down regulator is configured to receive, at the input terminal of the step-down regulator, the intermediate voltage signal from the output terminal of the flying switched-inductor regulator and provide, to the output terminal of the step-down regulator, the final voltage signal using a predetermined configuration of the plurality of capacitors; and a level shifting regulator comprising an input terminal, an output terminal, a flying capacitor, and a plurality of switches, wherein the level shifting regulator is configured to receive, at the input terminal of the level shifting regulator, the final voltage signal of the step-down regulator and to provide, at the output terminal of the level shifting regulator, the second voltage signal that is based on the final voltage signal of the step-down regulator.
