    Abstract: We describe an input buffer having a stabilized operating point and an associated method. An input buffer may include a first differential amplifying unit to generate a first output signal having a first operating point and a second differential amplifying unit to generate a second output signal having a second operating point. An output control circuit varies respective weights of the first and second output signals responsive to an output control signal. The first differential amplifying unit may operate responsive to a reference voltage and an input voltage signal. The second differential amplifying unit may operate responsive to the reference voltage and the input voltage signal. The first operating point may be relatively higher than the second operating point.

    Abstract: A backlight inverter for an LCD panel of an asynchronous pulse width modulation (PWM) driving type which is capable of driving a plurality of cold cathode fluorescent lamps (CCFLs) in pairs and controlling a plurality of PWM drive signals for respective operations of the lamps to make the phases thereof different. The backlight inverter comprises a main driving integrated circuit (IC), at least one sub-driving IC, and a plurality of lamp operating circuits for operating the pairs of lamps in response to the first and second PWM drive signals and the third and fourth PWM drive signals, respectively. The lamps have different PWM on/off periods so that overshoot of a power supply circuit can be reduced so as to keep the entire system power stable.

    Abstract: A positive-displacement oil pump is disclosed. In the oil pump, an insert body is fitted into a central opening of a shaft body to a height of an oil-feeding hole. The insert body is rotated along with the shaft body, and includes a central hole formed in the insert body, a cylindrical lip formed around an outlet of the central hole, a fluid discharge diode provided in an inlet of the central hole, and an inclined groove formed around an outer circumferential surface of the insert body such that the inclined groove forms a closed curve. A piston is movably fitted over the insert body such that the piston is axially moved while changing a volume of a displacement space defined between the insert body and the piston.

    Abstract: A single-ended sense amplifier and a memory device including the same are presented. A sense amplifier, which senses and amplifies data of a memory cell, may include a precharge circuit pre-charging a data line which is connected to the memory cell and provides a sensing voltage, and a reference line which provides a reference voltage, with a power supply voltage; a reference voltage generating circuit which generates the reference voltage by discharging the reference line based on a reference current, and adjusts an amount of the reference current based on the data of the memory cell; and a comparator which compares the sensing voltage and the reference voltage, and outputs a comparison result as the data of the memory cell.
