  • Publication number: 20140125410
    Abstract: A power amplifier (PA) which improves dynamic range of previous ZVS contour-based power amplifier architectures is presented. The inventive circuit combines ZVS contour-based power amplification with a current mode digital-to-analog converter (DAC) based digital polar power amplifier. The inventive elements interoperate to provide high efficiency even at large peak power back-off levels and increased dynamic range. The invention is particularly well-suited for use in modulation schemes (e.g., WLAN/LTE/WIMAX) having large peak-to-average output power ratios. Utilizing the inventive PA in generating modulation in these systems can increase RF transmitter efficiency of by approximately two-fold.

  • Patent number: 8606231
    Abstract: A combination of a radio receiver with a detachable controller that determine sends either reduced or enhanced metadata about received programming to the detachable controller based upon periodic authorization. A connection from the detachable control device to the radio receiver carries commands to the radio receiver and carries only the reduced set of metadata, such as tuned channel and tuned channel name, from the radio receiver to the controller. The controller is authorized by sending a radio identifier from the radio receiver to the control device, determination of an authentication code at the controller and communication of the determined authentication code back to the controller for validation. Upon validation, an enhanced set of metadata, including song title and artist, is sent to the controller. The enhanced metadata, the reduced metadata, or both, are optionally able to be encrypted. The radio receiver periodically performs this authorization processing.
