  • Patent number: 7433393
    Abstract: A method of operating a radio-frequency (RF) circuitry and a signal-processing circuitry in a mobile telephone apparatus includes at least partially disabling the signal-processing circuitry while transmitting or receiving signals. In one example, a processor is efficiently disabled by generating and servicing an interrupt of relatively high priority. One advantage of this example is that preexisting, legacy code can be maintained, while still achieving the desired objectives. The processor can be enabled by generating and servicing a second high priority interrupt.

  • Publication number: 20080241764
    Abstract: The present invention provides a method of lithographic patterning in order to the strength of the patterned photoresist. The method comprises: applying to a surface to be patterned a photoresist (18) comprising a polymer resin, a photocatalyst generator which generates a catalyst on exposure to actinic radiation, and a quencher; and exposing the photoresist (18) to actinic radiation through a mask pattern (12). This is followed, in either order, by carrying out a post-exposure bake; and developing the photoresist (18) with a developer to remove a portion of the photoresist which has been exposed to the actinic radiation. The polymer resin is substantially insoluble in the developer prior to exposure to actinic radiation and rendered soluble in the developer by the action of the catalyst, and wherein the polymer resin is crosslinked by the action of the quencher during the bake.

  • Publication number: 20080237705
    Abstract: The LDMOS transistor (1) of the invention comprises a substrate (2), a gate electrode (10), a substrate contact region (11), a source region (3), a channel region (4) and a drain region (5), which drain region (5) comprises a drain contact region (6) and drain extension region (7). The drain contact region (6) is electrically connected to a top metal layer (23), which extends over the drain extension region (7), with a distance (723) between the top metal layer (23) and the drain extension region (7) that is larger than 2?m. This way the area of the drain contact region (6) may be reduced and the RF power output efficiency of the LDMOS transistor (1) increased. In another embodiment the source region (3) is electrically connected to the substrate contact region (11) via a suicide layer (32) instead of a first metal layer (21), thereby reducing the capacitive coupling between the source region (3) and the drain region (5) and hence increasing the RF power output efficiency of the LDMOS transistor (1) further.

  • Publication number: 20080242246
    Abstract: A transmitter has a power amplifier (40) to amplify an input signal having amplitude modulation, a supply voltage controller (10) to control a supply voltage of the power amplifier (40) according to the envelope, a sensor (R1) for sensing a modulation of a current drawn by the power amplifier (40), a delay detector (20) for detecting a delay of the controlled supply voltage relative to the sensed current, and a delay adjuster (30) for compensating the relative delay according to the detected delay. By sensing a current drawn, the delay detected can include any delay contributed by the power amplifier (40) up to that point, and yet avoid the more complex circuitry needed to derive the delay from an output of the power amplifier. Thus the distortion and out of band emissions caused by differential delays can be reduced more effectively.

  • Publication number: 20080231385
    Abstract: An oscillator circuit has a first and a second piezoresistive resonator (1,2), each having a resonant frequency, each piezoresistive resonator having an input for driving the resonator, and each piezoresistive resonator having its input coupled directly to an output of the other of the resonators, to provide feedback according to a resistance of the respective resonator without amplification and without a phase shifter. This enables feedback without the need for another component to provide the phase shift. This means a simpler circuit can be used, which can facilitate greater integration and hence lower costs. By using piezoresistive resonators the need for an external crystal can be avoided, enabling greater integration and lower costs.

  • Publication number: 20080234967
    Abstract: A method for defining a sequence of tests for testing a plurality of electronic devices including integrated circuits is disclosed. A reference group of devices is defined (110), after which the devices in said group are subjected to all available tests under consideration (120). For each test, the test results are collected, from which a fault coverage metric of the test for the group of devices is extracted (130). Next, a test benefit is calculated for each test (140), which is a ratio between the fault coverage metric and the test duration of said test. The test sequence is built by repeatedly adding tests to the sequence on the basis of their test benefits (160) until the overall fault coverage of the test sequence has reached a predefined threshold (170). Consequently, a test sequence that is optimized in terms of test cost is obtained.
