stem System and method for pre-charging a current mirror By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT A system for pre-charging a current minor includes a controller configured to provide a first current and an additional current to a current minor to rapidly charge a capacitance associated with the current minor based on a reference voltage or control signals. A power amplifier module includes at least one current minor and a controller. A capacitor is coupled to the current minor. The controller provides a bias current in an amount proportional to an input to a voltage-to-current converter. The controller receives a control signal that directs the controller to apply one of a pre-charge voltage and a nominal voltage to the voltage-to-current converter. Full Article
stem Multimode differential amplifier biasing system By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT Differential power amplifier circuitry includes a differential transistor pair, an input transformer, and biasing circuitry. The base contact of each transistor in the differential transistor pair may be coupled to the input transformer through a coupling capacitor. The coupling capacitors may be designed to resonate with the input transformer about a desired frequency range, thereby passing desirable signals to the differential transistor pair while blocking undesirable signals. The biasing circuitry may include a pair of emitter follower transistors, each coupled at the emitter to the base contact of each one of the transistors in the differential transistor pair and adapted to bias the differential transistor pair to maximize efficiency and stability.

stem Power distortion-based servo control systems for frequency tuning RF power sources By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A radio frequency system includes a power amplifier that outputs a radio frequency signal to a matching network via a transmission line between the power amplifier and the matching network. A sensor monitors the radio frequency signal and generates first sensor signals based on the radio frequency signal. A distortion module determines a first distortion value according to at least one of (i) a sinusoidal function of the first sensor signals and (ii) a cross-correlation function of the first sensor signals. A first correction circuit (i) generates a first impedance tuning value based on the first distortion value and a first predetermined value, and (ii) provides feedforward control of impedance matching performed within the matching network including outputting the first impedance tuning value to one of the power amplifier and the matching network.
