Mobile communication terminal

An apparatus and method for reducing power consumption in a mobile communication system are provided. The apparatus includes a time slicing processor. When a frame border of the last section for determining a burst reception end time is not detected during a burst reception operation, the time slicing processor receives a burst enough to restore the whole MPE-FEC frame to the former state or receives an early burst reception end request for notifying that it is impossible to restore the whole MPE-FEC frame to the former state, and terminates the burst reception process.

An apparatus and for preventing a glitch in a clock switching circuit includes a select signal manager and a clock gate unit. The select signal manager generates a detect change signal, provides the detect change signal as an input signal for generating a clock gate signal to the clock gate unit, and changes a muxsel signal into a select signal using the clock gate signal to select a clock intending for switching. Upon receiving the detect change signal, the clock gate unit gates a received clock, generates the clock gate signal using a level of the detect change signal as an input signal, and provides the generated clock gate signal to the select signal manager.

Some embodiments of the present invention provide high voltage transistors including a semiconductor substrate and a device isolation film defining an active region in the semiconductor substrate. A gate electrode extends along a central portion of the active region while maintaining a predetermined width on the semiconductor substrate. A second well is formed on both sides of the gate electrode in the semiconductor substrate, and partially extends to a bottom surface of the device isolation film. The active region in the semiconductor substrate comprises a first active region disposed under the gate electrode, and separating the device isolation film and a second active region defined by the first active region and the device isolation film. Methods of manufacturing high voltage transistors are also provided.
