  • Device and method for generating chaotic signal
    Patent number: 7945045
    Abstract: Provided is a device for generating a chaotic signal comprising a PN signal generator that is composed of a digital logic circuit and generates a digital pseudo random signal with a predetermined frequency; a voltage control that generates a clock signal with a predetermined frequency; a mixer that mixes the pseudo random signal and the clock signal so as to generate a chaotic signal to output; and a band-pass filter that filters the chaotic signal, output from the mixer, into a chaotic signal of a desired band and then outputs the filtered signal.

  • Current mode logic-CMOS converter
    Patent number: 7405600
    Abstract: A current mode logic (CML)-CMOS converter comprises an input stage that is turned on/off by receiving an input voltage from the outside; a voltage control unit that outputs a constant voltage; a first switching unit that is connected to the input stage and the voltage control unit and is turned on/off by the constant voltage applied from the voltage control unit; and a second switching unit that is connected to the input stage and is turned on/off by a signal applied from the input stage.
