  • Publication number: 20170063324
    Abstract: Circuits, devices and methods are disclosed, including a phase shifter comprising a first node and a second node, and a first transmission line element having an inductance and a variable capacitance on each side of the inductance, the variable capacitance configured to provide a plurality of capacitance values to yield corresponding phase shift values based on an increment having a magnitude that is less than 90 degrees. In some implementations, the phase shifter further comprises a second transmission line element in series with the first transmission line element, the second transmission line element having an inductance and a variable capacitance on each side of the inductance configured to extend an overall phase shift range provided by the phase shifter.

  • Patent number: 9531392
    Abstract: Disclosed are systems and method for controlling frequency synthesizers. A control system can be implemented in a phase-locked loop (PLL), such as a Frac-N PLL of a frequency synthesizer, to reduce or eliminate reference spurs. In some embodiments, such a control system can include a phase detector configured to receive a reference signal and a feedback signal. The phase detector can be configured to generate a first signal representative of a phase difference between the reference signal and the feedback signal. The control system can further include a charge pump configured to generate a compensation signal based on the first signal. The control system can further includes an oscillator configured to generate an output signal based on the compensation signal. The compensation signal can be configured to reduce or substantially eliminate one or more reference spurs associated with the frequency synthesizer.

  • Publication number: 20160299997
    Abstract: A method and system provide a complete energy analytical model. An input model is acquired and consists of a combination of architectural building elements (ABEs) and conceptual massing elements (CMEs). The input model is pre-processed by extracting information from both the ABEs and the CMEs, and constructing virtual elements that encapsulate the extracted information. A discrete set of points in three-dimensional (3D) space that is distributed over boundary faces of the ABEs or CMEs is determined. The discrete set of points is used to provide a representation of the input model that is used in combination with a 3D cubical grid (a voxel grid) to analyze a spatial structure of the input model. A two-dimensional (2D) discrete approximation of the geometry of the input model is used to determine surfaces of the energy analytical model which is then output.
