1. A square wave generator suitable for use with an electrosurgical device, the square wave generator comprising:
- a waveform synthesizer configured to generate a waveform;
an amplifier operatively coupled to the waveform synthesizer for providing electrosurgical energy in a shape of square waves directly to tissue;
at least one sensor configured to sense an operational parameter of the electrosurgical energy outputted from the amplifier and to provide a sensor signal corresponding thereto; and
a controller adapted to receive the sensor signal and in response thereto control the waveform synthesizer.

Abstract
A square wave generator suitable for use with an electrosurgical device is provided. The square wave generator includes a voltage source configured to output a waveform and a comparator operatively coupled to the voltage source and configured to output energy in the form of a square wave. The generator may also include at least one sensor configured to sense an operational parameter of the energy outputted from the comparator and to provide a sensor signal corresponding thereto and a controller adapted to receive the at least one sensor signal and in response thereto control the voltage source.
