摘要： An amplifier may include control circuitry that may track a first input signal parameter and, in response, adjust a value of a second input parameter. Input parameter tracking and adjustment may facilitate control of output parameters for the amplifier. For example, an envelope-tracking amplifier may track input signal amplitude and adjust other input parameters in response. The adjustments may facilitate control of output parameters, such as gain or efficiency. The amplifier may further include calibration circuitry to determine adjustment responses to various tracked input parameters.

摘要： Apparatus and methods for envelope tracking systems are provided. In certain configurations, an envelope tracking system includes a digital filter that generates a filtered envelope signal based on a digital envelope signal representing an envelope of a radio frequency signal, a buck converter controllable by the filtered envelope signal and including an output electrically connected to a power amplifier supply voltage, a digital-to-analog converter module including an output electrically connected to the output of the buck converter and that provides an output current, and a digital shaping and delay circuit configured to generate a shaped envelope signal based on shaping the filtered envelope signal. The shaped envelope signal controls a magnitude of the output current, and the digital shaping and delay circuit controls a delay of the shaped envelope signal to align the output of the digital-to-analog converter module and the output of the buck converter.

摘要： This disclosure relates generally to power amplification devices and methods of operating the same. The power amplification devices are capable of reducing (and possibly cancelling) modulation of a ripple variation of a supply voltage level of a supply voltage onto a radio frequency (RF) signal. In one embodiment, a power amplification device includes a power amplification circuit configured to amplify an RF signal with a supply voltage such that a ripple variation in a supply voltage level of the supply voltage is modulated onto the RF signal in accordance with a conversion gain. However, the power amplification device also includes a plurality of ripple rejection circuits. The plurality of ripple rejection circuits is configured to produce phase shifts and one or more amplitude shifts in the RF signal so as to reduce the conversion gain of the power amplification circuit.

摘要： A circuit arrangement compensates for signal damping while transmitting transmission signals of a wireless mobile device. The circuit arrangement contains an adjustable signal level amplifying device which has a signal amplifier for amplifying the transmission signals with a signal amplification generated by the signal amplifier. The circuit further has an adjusting device for adjusting a resulting signal amplification, and a detector arrangement which detects whether a signal level of the transmission signal of the mobile device has exceeded an upper threshold and whether the signal level has reached a lower threshold. The detector arrangement causes the adjusting device to reduce the resulting signal amplification generated by the signal level amplifying device if the signal level has reached the upper threshold. The detector arrangement causes the adjusting device to reduce the resulting signal amplification generated by the signal level amplifying device if the signal level has fallen below the lower threshold.

摘要： A signal-processing system has an amplifier that generates an amplified (RF) output signal based on an (RF) input signal. The amplifier receives a supply voltage that can be selectively set to an appropriate level between a lower power supply level and a higher power supply level. With one power supply permanently connected to the supply voltage node, a control unit executes software to toggle a supply switch to periodically connect and disconnect the other power supply thereby generating a weighted average value for the supply voltage between the two power supply levels. When a sudden and large increase occurs in the (input) power level, hardware-interrupt circuitry interrupts and supersedes the software-based control of the supply-voltage switch to quickly switch the supply voltage towards the higher power supply level. The hardware-interrupt circuitry handles such situations faster than the software-based control in order to prevent a limit violation of spectrum emission requirements.
