POWERING IC CHIPS USING AC SIGNALS

摘要

A power converter within an integrated circuit ("IC") for providing DC power to one or more function circuit, where the power converter has a transformer circuit for receiving an AC power signal and for supplying a transformed AC power signal. A converter circuit receives the transformed AC power signal and then converts the signal into a DC power signal supplied to one or more function circuit. The transformed AC power signal might either be stepped up or stepped down. The transformer circuit might comprise two coils, where a first coil is magnetically coupled to a second coil. The first coil is a first spiral and the second coil is a second spiral wherein an insulating material layer is disposed between the first spiral and the second spiral. The transformer circuit might include transformers connected in parallel or in series and may further be connected correspondingly to more than one converter circuit coupled in parallel. An IC comprising the power converter circuit can be integrated into a computer system.
