A circuit for radiofrequency devices applicable to living tissues and device containing same. The supply circuit for the electrodes comprises a series resonant filter and a parallel resonant filter, synthonized to admit the fundamental signal of the input signal and simultaneously and exponentially attenuate the remaining harmonics by increasing the frequency thereof, in such a way that the input signal with harmonics only passes the fundamental signal without attenuation to the output, while the harmonics causing interferences are increasingly attenuated as their frequency is raised. |
