Patent number: 8908751Abstract: One embodiment of the present invention relates to a method and apparatus are provided herein for reducing the power consumption of a transmission chain while maintaining an acceptable figure of merit (e.g., linearity). In one embodiment, an adaptive biasing element is configured to perform adaptive biasing to reduce current consumption of a transmission chain by adjusting the operating point of one or more transmission chain elements (e.g., power amplifier, mixer, etc.). However, since adaptive biasing may reduce the linearity of a transmitted signal, its use is limited by the degradation of figure of merit caused by the introduced non-linearities. Accordingly, a pre-distortion element may be configured to perform adaptive digital pre-distortion (DPD) on a transmission chain input signal to account for non-linearities generated through the adaptive biasing, therefore allowing the adaptive biasing to further reduce the current consumption while maintaining an acceptable figure of merit.Type: GrantFiled: February 28, 2011Date of Patent: December 9, 2014Assignee: Intel Mobile Communications GmbHInventors: Andrea Camuffo, Chi-Tao Goe, Bernhard Sogl, Sandro Pinarello, Jan-Erik Mueller, Nick Shute

Patent number: 8364103Abstract: One embodiment of the present invention relates to a transmission circuit configured to dynamically adjust a number of active transistor cells within a power amplifier based upon a signal quality measurement determined from a feedback. The transmission circuit comprises a transmission chain having a power amplifier configured to provide an output signal. A feedback loop extends from the output of the power amplifier to a control circuit and is configured to provide measured information about output signal (e.g., phase, amplitude, etc.) to the control circuit. The control circuit utilizes the measured signal information to evaluate a measured signal quality of the output signal. The control circuit dynamically adjusts a number of active transistor cells within a power amplifier based upon a signal quality measurement until the power amplifier is optimized to operate at an operating point for low current and good transmission quality.Type: GrantFiled: September 21, 2010Date of Patent: January 29, 2013Assignee: Intel Mobile Communications GmbHInventors: Sandro Pinarello, Andrea Camuffo, Chi-Tao Goe, Nick Shute, Jan-Erik Mueller
