摘要:
An electrosurgical system is disclosed. The system includes a radio frequencyoutputstage configured to output at least one radio frequency waveform and a currentsensor coupled tothe output stage and configured to output a first differentiated signalcorresponding to a currentof the at least one radio frequency waveform, the current sensor coupled to afirst conditioningcircuit configured to integrate the first differentiated signal to output aprocessed current signalindicative of the current. The system further includes a voltage sensorcoupled to the outputstage and configured to output a second differentiated signal corresponding toa voltage of the atleast one radio frequency waveform, the voltage sensor coupled to a secondconditioning circuitconfigured to integrate the second differentiated signal to output a processedvoltage signalindicative of the voltage, wherein the first and second conditioning circuitshave a substantiallysimilar bandpass and phase response.
