1. A portable device, comprising:
- a near distance antenna receiving a first power source signal in an electromagnetic inductive coupling scheme;
a long distance antenna receiving a second power source signal in a magnetic resonance scheme;
a first power generation circuit generating a power source from the first power source signal, including a first voltage controller that removes a ripple in the power source, and a first protector generating a first charge state control signal;
a second power generation circuit generating a power source from the second power source signal; and
a battery charged with the generated power source, wherein the first charge state control signal represents a charged state of the battery, and wherein the first protector provides the power source, from which the ripple is removed, to the battery in response to a first charge enable signal.

Abstract
Provided is a portable device. The portable device includes a near distance antenna, a long distance antenna, a first power generation circuit, a second power generation circuit, and a battery. The near distance antenna receives a first power source signal in an electromagnetic inductive coupling scheme. The long distance antenna receives a second power source signal in a magnetic resonance scheme. The first power generation circuit generates a power source from the first power source signal. The second power generation circuit generates a power source from the second power source signal. The battery is charged with the generated power source.

12. A battery charging method of portable device, the battery charging method comprising:
-
receiving a power source signal through at least one antenna of a near distance antenna and a long distance antenna according to a separated distance from a charger; changing the power source signal into an Alternating Current (AC) power source; removing a ripple of the AC-converted power source; and providing the power source, from which the ripple is removed, to a battery based on a charged state of the battery, wherein the near distance antenna uses an electromagnetic inductive coupling scheme, and the long distance antenna uses a magnetic resonance scheme. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
