One method includes generating at least one dynamically adjustable phase shifted signal from the transmission signal. The transmission signal and the at least one dynamically adjustable phase shifted signal are separately amplified. The amplified transmission signal and the amplified at least one dynamically adjustable phase shifted signal are combined within a multiport network. An output signal for each of the plurality of antennas is generated by the multiport network.

Abstract: A mobile electronic device includes a display having a pixel and processing circuitry separate from but communicatively coupled to the display. The processing circuitry prepares image data to send to the pixel and adjusts the image data to compensate for operational variations of the display based on feedback received from the display that describes a present operational behavior of the pixel. The mobile electronic device also includes additional electronic components that affect the present operational behavior of the pixel depending on present operational behavior of the additional electronic components.

Abstract: A transconductance cell (100) is disclosed that includes a first transistor (101) and a second transistor (102). A regulator (107) regulates an average voltage in response to a reference voltage (150), where the average voltage corresponds to the average of a voltage at a bias terminal of the first transistor and a voltage at a bias terminal of the second transistor. A mixer including the transconductance cell is also disclosed. In the mixer, the transconductance cell receives a differential input voltage and produces a differential output current. The mixer also includes one or more switches that multiply the differential output current with an oscillator signal. A method is disclosed that includes measuring an average voltage of a voltage at a bias terminal of a first transistor and a voltage at a bias terminal of a second transistor and regulating the average voltage responsive to the measured average voltage and a reference voltage.

Abstract: Apparatus, systems, and methods implementing techniques for estimating a relative rotation between a first complex signal and a second complex signal. The first complex signal is quantized (410) to produce a quantized signal, and the quantized signal and an additional signal are combined (420), where the additional signal corresponds to the second complex signal. An estimate of a relative rotation between the first complex signal and the second complex signal is generated in accordance with the combined signal.
