  • Patent number: 8979362
    Abstract: A circuit for sensing a physical quantity according to an embodiment of the present invention includes a first oscillator circuit configured to provide a first clock signal including a first frequency depending on the physical quantity, and a second oscillator circuit configured to provide a second clock signal comprising a second frequency depending on the physical quantity. The circuit also includes a frequency comparator circuit configured to provide a frequency signal indicative of the physical quantity, the frequency signal being based on the first and second frequencies, wherein the first and second oscillator circuits are configured to provide the first and second clock signals such that due to a change in the physical quantity one frequency of the first and second frequencies increases, while the other frequency of the first and second frequencies decreases.

  • Patent number: 8195995
    Abstract: A integrated circuit comprises a circuit part to be protected and protective lines located at least one wiring level of the integrated circuit. In addition, the integrated circuit comprises logical gates coupled to the protective lines, whereby a logic circuit is formed, and a processing unit implemented to detect a manipulation of the integrated circuit by applying test patterns to the logic circuit and verifying a logic output value of the logic circuit responsive to the test patterns.

  • Patent number: 7865755
    Abstract: A frequency regulator for varying a clock frequency of a power-supplied consumer operated in a clocked manner, wherein the frequency regulator is implemented to perform an overall variation of the clock frequency from an actual frequency to a set frequency, such that the overall variation is obtained by a plurality of clock changes, each with a different amount of change, wherein each of the respective amounts of change depends on a power change caused by the associated clock frequency change.

  • Patent number: 7495502
    Abstract: A circuit arrangement including a voltage supply device, which has an output, and that provides a variable supply voltage, a supply-voltage-controlled clock generator, which is coupled to the output of the voltage supply device, and that provides a system clock signal having a variable effective system clock frequency, a circuit section having a supply terminal, which is coupled to the output of the voltage supply device, and a clock input, which receives the system clock signal, and a regulating device that determines a supply-voltage-dependent supply current value and detects the extent to which the supply current value lies within a predetermined current value range, and which is coupled to the voltage supply device such that the supply voltage is regulated based on whether the supply current value lies within the predetermined current value range.
