Publication number: 20150319721Abstract: Embodiments of this disclosure include methods in which spurs generated by the drifting of an oscillation frequency of an oscillation signal provided by a free-running oscillator may be minimized and/or eliminated from an output signal of a phase locked loop (PLL). Methods include minimizing the mixing gain between the oscillation signal and a power signal provided to the PLL. The oscillation signal and the power signal may be mixed in a phase frequency detector (PFD) included in the PLL. The minimizing of the mixing gain for the PFD also minimizes the degrading effect that the spurs have on the overall performance of the communications device. The mixing gain may be minimized by minimizing the impedance provided at nodes included in the PFD where the oscillation signal and the power signal mix. The mixing gain may also be minimized by maximizing the power supply rejection ratio for the PFD.Type: ApplicationFiled: June 30, 2015Publication date: November 5, 2015Applicant: Broadcom CorporationInventors: Nikolaos HARALABIDIS, Ioannis Kokolakis, Georgios Konstantopoulos

Patent number: 9178968Abstract: Frame formatting for communications within single user, multiple user, multiple access, and/or MIMO wireless communications. A signal is processed within a communication device using at least two respective downclocking ratios (e.g., a first downclocking ratio applied to a first portion of the signal such as a frame or packet extracted there from, a second downclocking ratio applied to a second portion of the signal). Alternatively, a signal is divided into more than two respective portions, and different respective downclocking ratios are applied to those different respective portions (e.g., a first downclocking ratio applied to a first portion of the signal, and so on up to an n-th downclocking ratio applied to an n-th portion of the signal). Some implementations apply a singular or common downclocking ratio to more than one portion of the signal (which may be contiguous/adjacent or non-contiguous/non-adjacent within the signal).Type: GrantFiled: April 12, 2013Date of Patent: November 3, 2015Assignee: Broadcom CorporationInventor: Ron Porat
