Abstract: A system and method of generating RF includes an RF generator, a variable DC power supply, and a comparator. The RF generator has an RF output coupled to an input of the transducer. The variable DC power supply has a control input and a DC output coupled to the RF generator. The comparator includes a first input coupled to a set point control signal, a second input coupled to the RF generator RF output, and a control signal output coupled to a voltage control input on the variable DC power supply.

Abstract: A system and method of providing RF to a transducer includes an oscillator, an RF generator, and a voltage phase detector. The oscillator has a frequency control input and an RF signal output. The RF generator has an input coupled to the oscillator RF signal output and an RF generator output coupled to the transducer. The voltage phase detector includes a first phase input coupled to the RF signal output of the oscillator, a second phase input coupled to the RF generator output, and a frequency control signal output coupled to the oscillator frequency control voltage input.
