摘要： A phase synchronous multiple LC tank oscillator includes a plurality of oscillator stages that are configured to oscillate synchronously. The phase of each of the plurality of oscillator stages is substantially the same and the plurality of oscillators are inductively coupled. The synchronous oscillation is substantially caused by magnetic coupling. The oscillator stages may be electrically coupled during a first time period and the electrical coupling and disconnected or reduced during a second time period.

摘要： A precharge circuit that initializes an electronic filter to a middle voltage level of an operational voltage includes a filter isolation device, a filter communication device, and an initializing device. The filter isolation device isolates the electronic filter from electronic circuits connected to an input and an output of the electronic filter to segregate the electronic filter from the electronic circuits connected to the input and the output of the electronic filter during a precharge time. The filter communication device allows communication between the precharge circuit and the electronic filter for initializing the charge state during the precharge time. The initializing device provides an initializing signal to the charge state of the electronic filter during the precharge time. The precharge circuit further has a biasing device in communication with the initializing device to provide a mid level control signal providing a reference level of the charge state.

摘要： The present invention provides a method (200) and an apparatus (100) for spatially adaptive filtering for video encoding. The apparatus filters a video sequence prior the encoding process. The apparatus comprises a noise variance determiner (102), a local variance determiner (104), a noise visibility function determiner (106), a Gaussian kernel determiner (108), and a convolver (110). The apparatus removes noise directly from a Displaced Frame Difference, DFD, signal. This novel approach removes noise and miscellaneous high frequency components from the DFD signal without the introduction of the filtering artifacts characteristic of current techniques. By reducing the miscellaneous high frequency components, the present invention is capable of reducing the amount of information that must be encoded by the video encoder without substantially degrading the decoded video sequence.

摘要： Calibrating a filter is disclosed. The filter is reconfigured as an oscillator during calibration. Switches and/or other implementations of reconfiguring a filter are used to reconfigure the negative feedback loop of the filter to a positive feedback loop. The oscillation parameters are then measured to adjust the components of the filter to achieve an oscillation that corresponds to a desired filter characteristic.

摘要： A communications system comprises a local oscillator configured to generate a local oscillator output and a signal processing component coupled to the local oscillator. The signal processing component is configured to receive a clock signal and the clock signal is derived from the local oscillator output. A method of demodulating an input signal comprises deriving a conversion signal from a local oscillator output, deriving a clock signal from the local oscillator output, mixing the input signal with the conversion signal to generate an intermediate frequency signal, and processing the intermediate frequency signal using a signal processing component driven by the clock signal. A method of modulating an input signal comprise deriving a conversion signal from a local oscillator output, deriving a clock signal from the local oscillator output, processing the input signal using a signal processing component driven by the clock signal to generate an intermediate frequency signal and mixing the intermediate frequency signal with the conversion signal to generate a modulated signal.
