摘要： A signal generator, a signal generating method, and an RF communication system adopting the same are provided to simply change the frequency band of an outputted chaotic signal by changing the filtering band of a BPF used as a filter. First to third amplifiers(31,33,35) are connected in a ring shape. A coupler(37) is disposed in the ring to form a closed loop together with the first to third amplifiers(31,33,35), feeds back a portion of a signal to at least one of the first to third amplifiers(31,33,35), and outputs signals formed by the first to third amplifiers(31,33,35). The first amplifier(31) receives a signal from the coupler and amplifies it at a certain amplification ratio. The second amplifier(33) receives an amplified signal from the first amplifier(31) and generates a harmonic component of a frequency. The third amplifier(35) clips a signal from the second amplifier(33) to a certain level.

摘要： A mobile terminal having an RFID(Radio Frequency IDentification) system is provided to prevent an RFID Tx carrier leakage signal from being inputted to an RFID receiving circuit by separating an RFID transmitting antenna from an RFID receiving antenna and to achieve the miniaturization of the mobile terminal by using the RFID transmitting antenna as an antenna for mobile communication in common. A mobile terminal having an RFID system, which reads information from an RFID tag arranged within a certain distance, comprises an RFID transmitting antenna(110) and an RFID receiving antenna(120). The RFID transmitting antenna(110) transmits a radio signal to the RFID tag. The RFID receiving antenna(120), installed separately from the RFID transmitting antenna(110), receives an RFID radio signal from the RFID tag. The RFID transmitting antenna(110) is manufactured in the form of a whip antenna, a PIFA(Planar Inverted F Antenna) or a patch antenna. The RFID transmitting antenna(110) is a main antenna which is used as an mobile communication antenna for transmitting/receiving mobile communication radio signals.

摘要： PURPOSE: A nonvolatile memory device and a manufacturing method of the same are provided to prevent the deterioration of a trap feature of a doped impurity in an active region by preventing the recess of a semiconductor substrate. CONSTITUTION: An element isolation film(104) is formed in a semiconductor substrate(100) in which a tunnel oxide film(102) and a first conductive film are formed. The element isolation film is defined into a first area(1) in which the conductive film remain and a second are from which the conductive film is removed. A dielectric film and the second conductive film are formed successively on the substrate to cover a first conductive film and the element isolation film. A certain width of a hard mask pattern is formed on the second conductive film to be perpendicular to the element isolation film.

摘要： A wireless communication device using a chaotic signal and a wireless communication method thereof are provided to implement a low-power, small-size wireless communication device by using a chaotic signal, compared with an existing wireless communication device. A wireless communication system comprises a transmitting terminal and a receiving terminal. The transmitting terminal generates a chaotic signal having plural frequency components at a specific frequency band, creates a chaotic carrier by inserting a data signal containing information to be delivered in the chaotic signal, and transmits it to the receiving terminal. The receiving terminal extracts the data signal from the chaotic carrier, transmitted from the transmitting terminal by wireless, and processes it. The transmitting terminal comprises a chaotic signal generator(30), a modulator(11), and an antenna(5). The chaotic signal generator(30) generates the chaotic signal. The modulator(11) combines the chaotic signal with the data signal and creates the chaotic carrier. The antenna(5) transmits the chaotic carrier. The receiving terminal comprises a detection part(23). The detection part(23) detects the chaotic carrier and extracts the data signal from the chaotic carrier.
