  • Publication number: 20100090778
    Abstract: A radio frequency filter (1) comprises an input impedance adaption section (2) and a tank capacitor section (3). Thereby, the capacity of the input impedance adaption section (2) does not comprise a fixed capacitor, it only comprises switchable capacitors. Further, the tank capacitor section (3) does not comprise a fixed capacitor as well it only comprises switchable capacitors. The capacity of the input impedance adaption section (2) can be tuned independent of the tank capacity, section capacity by means of switchable capacitors. Hence, bandwidth and frequency of the radio frequency filter can be modified independent of each other. The imput impendance adaption section (2) is connected in series between the input and output of the filter (1). The tank capacitor section (3) is shunt connected between the input-output series path of the filter (1) and ground.

  • Publication number: 20100090714
    Abstract: An integrated circuit has an inhomogeneous protective layer or coating over a circuit to be protected, and a sensing circuit (80) arranged to sense a first impedance of a part of the protective coating compared to a reference impedance (CO) located on the integrated circuit. The sensing circuit is able to measure a change in the first impedance, e.g. caused by tampering. The sensing circuit has an amplifier (OTA) having a feedback loop, such that the impedance being sensed is in the feedback loop. The sensing circuit can be incorporated in an oscillator circuit (OTA, Comp) so that the frequency depends on the impedance. Where the impedance is a capacitance, sensing electrodes adjacent to the protective layer or coating, form the capacitance. The electrodes can be arranged as selectable interdigitated comb structures, so that the protective layer or coating extends in between the teeth of the comb structures.

  • Patent number: 7696840
    Abstract: RF switches are known from the art for selecting an RF signal from a multiple of inputs. For instance a TV-tuner and TV-Front-end can have two or more antenna inputs but are implemented with a relative bad cost performance. The present invention relates to an RF selection switch circuit (200). The switch comprises a first switch (202), a second switch (204) with both an RF input port and a common RF output port a control signal circuitry (206). In a preferred embodiment the switches comprise pin-diodes. The RF output port comprises two transistors (T1, T2), one of which at a time can put the non-selected switch to a low-impedance level in order to minimize signal leakage the common output port.

  • Patent number: 7698514
    Abstract: A data processing system includes processing units for processing data, at least one memory for storing data from the processing units, an interconnect for connecting the processing units and the memory. The processing units request write access to the memory via the interconnect to write data into the memory. At least one arbiter performs interconnect arbitration for the access to the memory from the processing units, wherein interconnect arbitration is performed based on the minimum logic level changes of the interconnect as introduced by the write accesses of the processing units to the memory. If more than one write request is available from different processing units the interconnect arbitration (interconnect access), is granted to that processing unit, whose data to be sent to the memory via the interconnect results in minimum logic level changes to the interconnect. Power dissipation due to switching of logic levels is reduced.
