Mobile devices are getting more and more popular. The mobile phone in the market now has become a pocket media center. It contains at least a digital still camera, video conference functionality, an MP3 player with simulated surround sound, and a color Internet browser coupled with 3-D gaming capability. Mobile phones are continuously equipped with an increasing number of functions, and newer phones will come with higher resolution cameras, adding various kinds of storage attachment, mobile television and personal security devices such as thumbprint sensors. Mobile phone power management thus, becomes one of the most significant engineering challenges. Other than mobile phones, the other portable devices like handheld devices, Personal Digital Assistants (PDAs), Smart Phones, Portable Multimedia Players (PMPs), MP3 players, Gaming, and Global Positioning System (GPS) also present increasingly sophisticated functionality and application requirements.
