  • Patent number: 7680173
    Abstract: A system and method are provided for performing a spread spectrum clock generation, where the system includes self-adjusting delay line configured to spread the spectrum of a fixed circuit using a fixed clock frequency and a delay circuit configured to generate an adjustment signal to the delay line by adding or subtracting an addition delay per cycle, therefore causing a shift in the output clock frequency, wherein the amount of shift is proportional to the rate of addition or subtraction of delay.

  • Publication number: 20050215216
    Abstract: A sigma delta modulation loop circuit and related method is provided for use in a device having a radio frequency receiver. The loop is configured to compensate for noise that is generated by the sigma delta loop and that affects radio signals within the range of a radio frequency band according to the operating frequency of the radio frequency tuner.

  • Patent number: 6472959
    Abstract: A filter comprises a shallow bulk acoustic wave (SBAW) longitudinally coupled double mode resonator (LCR) and a reactance coupled between an input and an output of the resonator. Due to its use of a piezoelectric substrate with high electromechanical coupling and an orientation for propagating SBAWs, the resonator has a relatively poor stop band attenuation in a shoulder region on a high frequency side of its pass band. At frequencies in the shoulder region, a signal coupled via the resonator from the input to the output is reduced by a signal of opposite phase coupled via the reactance with a similar attenuation, thereby improving attenuation in the shoulder region. The reactance can be a capacitance formed on the substrate surface.
