  • Publication number: 20160036452
    Abstract: A method and system are disclosed for measuring a specified parameter in a phase-locked loop frequency synthesizer (PLL). In one embodiment, the method comprises introducing multiple phase errors in the PLL, measuring a specified aspect of the introduced phase errors, and determining a value for the specified parameter using the measured aspects of the introduced phase errors. In one embodiment, the phase errors are introduced repetitively in the PLL, and these phase errors produce a modified phase difference between the reference signal and the feedback signal in the PPL. In one embodiment, crossover times, when this modified phase difference crosses over a preset value, are determined, and these crossover times are used to determine the value for the specified parameter. In an embodiment, the parameter is calculated as a mathematical function of the crossover times. The parameter may be, for example, the bandwidth of the PLL.

  • Patent number: 9203159
    Abstract: Systems, methods, devices and apparatuses directed to transceiver devices are disclosed. In accordance with one method, a first set of antenna positions in a first section of a set of sections of a circuit layout for the circuit package is selected. The method further includes selecting another set of antenna positions in another section of the circuit layout such that an arrangement of selected antenna positions of the other set is different from an arrangement of selected antenna positions of a previously selected set of antenna positions. The selecting another set of positions in another section is iterated until selections have been made for a total number of antennas. The selecting the other set is performed such that consecutive unselected positions in the other section do not exceed a predetermined number of positions. In addition, antenna elements are formed at the selected positions to fabricate the circuit package.
