  • AMPLITUDE-SHIFT-KEYING (ASK) RADIO-FREQUENCY (RF) SIGNAL DECODING DEVICE AND METHOD THEREOF
    Publication number: 20120008720
    Abstract: An amplitude-shift-keying radio-frequency (ASK RF) signal decoding method includes separating a low frequency and a high frequency from an ASK RF signal, which includes a pause section and a non-pause section, generating a divided signal by dividing the high frequency signal, counting the divided signal for the non-pause section of the low frequency signal, and decoding the ASK RF signal based on a result of the counting.
    Type: Application

  • Voltage-glitch detection device and method for securing integrated circuit device from voltage glitch attack
    Patent number: 7085979
    Abstract: A voltage-glitch detection circuit includes a voltage comparator having two input terminals with different capacitance resistance charge/discharge time. Voltage dividers are coupled to the two input terminals of the voltage comparator respectively, and commonly receive a supply voltage. One of the voltage dividers is supplied to the voltage comparator as a reference voltage of the voltage comparator, and the other is supplied as a glitch detection voltage to the voltage comparator.
