Abstract
A RF generator includes a RF power source and a RF control module coupled to the RF power source. The RF control module is configured to generate at least one control signal to vary a respective at least one of an RF output signal from the RF power source or an impedance between the RF power source and a load. The RF output signal includes a RF signal modulated by a pulse signal, and the RF control module is further configured to adjust the at least one control signal to vary at least one of an amplitude or a frequency of the RF output signal or the impedance between the RF power source and the load to control a shape of the pulse signal. The at least one of the amplitude, the frequency, or the impedance is adjusted in accordance with respective feedforward adjustments that vary in accordance with a respective sensed pulse parameter detected between a matching network and the load.
