摘要： A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.

The plurality of gate finger electrodes are arranged pectinate on the surface of the active region of the semiconductor substrate. The two gate connection electrodes connect in common each of both ends of the plurality of gate finger electrodes. The plurality of source electrodes and the plurality of drain electrodes are arranged alternately on the surface of the semiconductor substrate between the plurality of gate finger electrodes. The plurality of drain connection elements connects in sequence the plurality of drain electrodes. The ratio of the inductance value of each drain connection element to the parasitic capacitance of the drain-source electrodes between the corresponding drain electrode and the source electrode is constant.

摘要： A receiver comprises a Low Noise Amplifier (LNA) configured to amplify an input signal and a resonant circuit coupled to the LNA. A first switch couples current from the resonant circuit to a first capacitor integrating a first voltage, wherein the first switch is enabled with a clock signal. A second switch couples current from the resonant circuit to a second capacitor integrating a second voltage, wherein the second switch is enabled with an inverse clock signal. A differential amplifier comprises a positive input for receiving the first voltage and a negative input for receiving the second voltage in order to produce a sum and a difference frequency spectrum between a signal spectrum carried within the current and a frequency of the clock signal.

摘要： A transimpedance amplifier includes a first and a second power supply terminal for receiving a positive constant supply voltage, wherein the second power supply terminal represents a ground, and an input terminal adapted to be connected to a current source. The transimpedance amplifier further comprises a transistor comprising a control terminal and two further terminals, wherein the input terminal is connected to the control terminal of the first transistor. An inductor is connected between the first of the two further terminals of the transistor and the first power supply terminal, and a bias network is connected between the second of the two further terminals of the transistor and ground. Specifically, the transimpedance amplifier is configured such that the resistance between said first of said two further terminals of said first transistor and said first power supply terminal is small enough, such that said transimpedance amplifier operates as a differentiator.

摘要： A high-power solid-state RFPA includes an output stage having a power transistor and a current enhanced driver that drives the output stage. The current enhanced driver includes an inductor and first and second transistors arranged in totem-pole-like configuration. When the first transistor is turned on and the second transistor is turned off, the inductor supplies a first charging current to the output stage, to assist in charging the input gate-source capacitor (Cgs) of the power transistor in the output stage. The first transistor further provides a second charging current that supplements the first charging current, thereby enhancing charging of the gate-source capacitor Cgs. Conversely, when the first transistor of the driver is turned off and the second transistor is turned on, the second transistor provides a discharge path through which the gate-source capacitor Cgs can discharge.

摘要： Apparatus and methods for calibration of envelope trackers are provided. In one embodiment, a power amplifier system includes a VGA that amplifies an RF input signal to generate an amplified RF input signal, a power amplifier that amplifies the amplified RF input signal to generate an RF output signal, and an envelope tracker that generates a supply voltage for the power amplifier. The envelope tracker includes a scaling module that generates a scaled envelope signal based on a power control level (PCL) signal and an envelope signal that changes in relation to an envelope of the RF input signal. The envelope tracker further includes a calibration module that controls an amount of scaling of the scaled envelope signal based on calibration data to compensate for an envelope amplitude misalignment of the envelope tracker. The envelope tracker controls the voltage level of the supply voltage based on the scaled envelope signal.
