  • Devices and Methods for Improving Yield of Scalable Periphery Amplifiers
    Publication number: 20160233842
    Abstract: Device and methods for improving consistency of operation and therefore yield of scalable periphery amplifiers is described. Amplifier size of the scalable periphery architecture can be adjusted to obtain part-to-part consistency of operating performance as per a defined/desired set of criteria. Amplifier segments of the scalable periphery architecture can be rotated to distribute wear. Further, extra amplifier segments can be implemented on amplifier dies to extend the overall lifetime of amplifiers.

  • Methods and Apparatuses for use in Tuning Reactance in a Circuit Device
    Publication number: 20160191019
    Abstract: Methods and apparatuses for use in tuning reactance are described. Open loop and closed loop control for tuning of reactances are also described. Tunable inductors and/or tunable capacitors may be used in filters, resonant circuits, matching networks, and phase shifters. Ability to control inductance and/or capacitance in a circuit leads to flexibility in operation of the circuit, since the circuit may be tuned to operate under a range of different operating frequencies.

  • Mismatch Detection using Replica Circuit
    Publication number: 20160116525
    Abstract: An apparatus for detecting an operating characteristic mismatch at an output of an amplifier by using a replica circuit is presented. In one exemplary case, a detected voltage difference at the output of the two circuits is used to drive a tuning control loop to minimize an impedance mismatch at the output of the amplifier. In another exemplary case, the replica circuit is used to detect a fault in operation in a corresponding main circuit. A method for detecting a load mismatch in a main RF circuit using the replica circuit is also presented.

  • Scalable Periphery Tunable Matching Power Amplifier
    Publication number: 20160087593
    Abstract: A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.

  • Systems and Methods for Minimizing Insertion Loss in a Multi-Mode Communications System
    Publication number: 20160020892
    Abstract: Methods and system for using a multifunctional filter to minimize insertion loss in a multi-mode communications system are described. Specifically described is a multifunctional filter that is configurable to operate in a band-pass mode when a first type of signal is propagated through the multifunctional filter, and to operate in a low-pass mode when a second type of signal is propagated through the multifunctional filter. The multifunctional filter presents a lower insertion loss to the second type of signal when operating in the low-pass mode than in the band-pass mode.
