Abstract
Disclosed are systems, devices, and methods for interdigitation of waveforms for dual-output electrosurgical generators. Such methods may comprise outputting DC energy from a power supply, converting DC energy from the power supply, by a plurality of amplifiers coupled to the power supply, into a plurality of RF waveforms, and controlling the plurality of RF amplifiers to interdigitate the first and second RF waveforms.

1-18. (canceled)
An electrosurgical generator, comprising:
- a plurality of RF amplifiers, each of the plurality of RF amplifiers configured to output an RF waveform of a plurality of RF waveforms;
- a plurality of pairs of output terminals, each pair including an active terminal and a return terminal, each of the pairs of output terminals is independently connected to one of the plurality of RF amplifiers and configured to independently connect to an electrosurgical instrument of a plurality of electrosurgical instruments;
- and
- a controller coupled to the plurality of RF amplifiers and configured to control the plurality of RF amplifiers to interdigitate the plurality of RF waveforms.
