Abstract: PURPOSE: An output power-supply control device outputs the output power-supply of various steps according to a transmission power level(i.e., output level), and reduces a power-consumption. CONSTITUTION: An output power-supply control device includes a battery(10), and converter(20) for converting a DC voltage applied to a battery to a predetermined level DC voltage. Resistors(R4¯R7) are serially connected between an output terminal of the converter and a ground terminal. The switches(50,60) are connected between contact points of the resistors and an output terminal of the converter, are turned on or off by a switching signal. A controller(70) outputs a switching signal which differently divides an output DC voltage of the converter according to a transmitting/receiving mode of the terminal and a transmission power level. Thereby, the output power-supply control device outputs the output power-supply of various steps according to the output level, and reduces a power-consumption.

Abstract: PURPOSE: A busy termination alarm method in a mobile terminal is provided to inform the user of a mobile terminal that a call has been terminated when the mobile terminal is in a traffic state. CONSTITUTION: In an idle state, a control part checks whether an alarm signal is generated(300,302). If an alarm signal is detected, the control part checks whether the mobile terminal is in a traffic state(304). In case that the mobile terminal is in a traffic state, the control part checks whether an earphone is connected(306). If the earphone is not connected, the control part outputs a vibration alarm through an oscillator(308). However, in case that the earphone is connected, the control part outputs a melody alarm through a speaker or a LED alarm through a LED(310).

Abstract: PURPOSE: A PLL(Phase Locked Loop) of a mobile communication terminal is provided to control comparison frequencies according to each output frequency, thereby making phase noise characteristics of a local oscillator better and improving noise characteristics of a receiver. CONSTITUTION: A reference oscillator(101) oscillates a reference frequency, and outputs the oscillated reference frequency. The first divider(103) divides the reference frequency as a basic frequency to output the basic frequency. A phase comparator(105) compares a phase of the basic frequency with a phase of a frequency inputted from the second divider(111), and applies an output proportioned to a phase difference to a loop filter(107). The loop filter(107) removes a harmonic component contained in the output, and outputs a control signal. A local oscillator(109) changes an oscillating frequency by the control signal, and outputs an output frequency. The second divider(111) divides the output frequency to output the frequency to the phase comparator(105). A PLL data generating unit(120) is composed of many PLL data generators(121,123,125) for controlling dividing ratios of the first and the second divider(103,111). A central processing unit(200) selects a specific PLL data generator according to the output frequency to drive the generator.
