    Inventors: Babak Mazda, Farzad Sahandiesfanjani, Adya Tripathi
  • Efficient RF amplifier topologies
    Publication number: 20070004343
    Abstract: Power-efficient front-end topologies for radio frequency power amplifiers are described which may be used to implement full-duplex transceivers for wireless mobile terminals such as, for example, cellular phones. At least some of the described topologies employ highly efficient power amplifiers having well-optimized global feedback loops with noise-shaping capability.

  • Digital-to-analog converter with level control
    Publication number: 20050035891
    Abstract: Methods and apparatus are described for converting a digital data stream to an analog signal. Charge is added to and subtracted from an input of an integrator in a manner representative of the digital data stream thereby generating the analog signal at an output of the integrator. The amount of charge is varied thereby controlling the output level of the analog signal.

  • Methods and apparatus for facilitating negative feedback, providing loop stability, and improving amplifier efficiency
    Patent number: 6621339
    Abstract: An amplifier is described having an amplification stage in a first feedback loop. The amplification stage is operable to open the first feedback loop during operation of the amplifier. The amplifier further comprises a feed forward path bypassing the amplification stage. The feed forward path is operable to provide a second feedback loop when the first feedback loop is open.
