    • A predistorter that linearizes the nonlinearity of a power amplifier in a system supporting a multimode and a multiband (frequency band). The predistorter includes a field-effect transistor, an impedance transform unit, a first inductor, a first capacitor, and a second capacitor. The field-effect transistor has a source connected to the ground and uses a variable gate bias voltage. The impedance transform unit is connected to a drain of the field-effect transistor to perform impedance transform. The first inductor is connected between the impedance transform unit and a voltage provided to the field-effect transistor. The first capacitor is connected between a power input terminal and the impedance transform unit. The second capacitor is connected between a power output terminal and the impedance transform unit.

    • In a method of estimating a leakage current in a semiconductor device, a chip including a plurality of cells is divided into segments by a grid model. Spatial correlation is determined as spatial correlation between process parameters concerned with the leakage currents in each of the cells. A virtual cell leakage characteristic function of a cell is generated by arithmetically operating actual leakage characteristic functions. A segment leakage characteristic function of a segment is generated by arithmetically operating the virtual cell leakage characteristic functions of all cells in the segment. Then, a full chip leakage characteristic function of the chip is generated by statistically operating the segment leakage characteristic functions of all segments in the chip. Accordingly, computational loads of Wilkinson's method for generating the full chip leakage characteristic function can remarkably be reduced.

    • The present invention relates to an apparatus and method for controlling power to a Universal Serial Bus (USB) device. The present invention provides an apparatus for controlling power to a USB device, the USB device being used to connect a Personal Computer (PC) with a peripheral device, the power control apparatus including a plug-in port for connecting the peripheral device with the PC, a state detector for detecting whether the peripheral device is in a preparation completion state, a power supply unit for supplying power to the USB device, and a power control unit for controlling the power supply unit so that power is supplied to the USB device if it is determined that the peripheral device is in a plugged-in state, and if it is determined that the peripheral device is in a preparation completion state by the state detector. Accordingly, the present invention performs the supply of power only when the peripheral device is plugged into the USB device and its internal application program is in a preparation completion state, so that it can prevent power from being unnecessarily consumed.
