Latest Patents
One of Rouse's latest patents is titled "Plasma generation systems with multi-dimensional impedance matching networks." This invention includes an impedance matching network that is calibrated to map desired matching network impedance values to the closest available settings of impedance control components. The tuning controller defines a set of target impedance values spaced apart throughout the tuning range and drives the matching network to generate a set of closest frame tuning values proximate to each target impedance value. The tuning controller computes interpolated tuning values between adjacent pairs of frame tuning values and stores a tuning database that maps available matching network impedance values to specific sets of settings for the impedance control components. After the calibration stage, the tuning controller automatically utilizes the tuning database to map desired matching network impedance values to available settings of the impedance control components on an ongoing basis. Representative embodiments include variable loading and tuning capacitors in series with a fixed or variable phase-shift inductor.
Another notable patent is for "Systems and methods for variable gain tuning of matching networks." This invention discloses a method and apparatus for utilizing a variable gain algorithm for adjusting a capacitor in an automatic RF impedance matching network. The apparatus may operate in a closed-loop feedback control system, with one or more error signals driving the capacitors within the system. To achieve a critically damped control system response, multiple operating regions for the matching network and its constituent elements may be identified, and a set of gains may be applied to the error signals in the control system when operating in those regions. An operating region may be defined by characteristics of the input signals measured by the apparatus, calculated by the apparatus, or the state of the apparatus itself.
