 · A continuous high-frequency waveform with a peak voltage of at least 200Vp will produce an intensity of current sufficient to create micro electric sparks between the active electrode and the target tissue. Such high-current density along the leading edge of the electrode causes cells to literally explode, separating the tissue as if it were cut.

 · U2 and U3 Op-Amps are high frequency with high input impedance, acting as triggers to help selecting signal amplitudes between the two voltage levels. At the end, after AND gate, we count pulses to measure signals between these two voltage levels (Fig. 5). The proportion of R6/R7 has direct relation with energy resolution.

This process involves applying an RF (Radio Frequency) spark between a probe and the tissue. The electric current through the tissue heats up the tissue and evaporates the water in the cell destroying it. This achieves special surgical effects namely cutting, coagulation and desiccation. The voltage on the electrode is between 1000 –10,000 V p-p.
