  • Publication number: 20250259821
    Abstract: A method of generating a voltage pulse includes generating a first non-sinusoidal continuous wave voltage (NSCWV) waveform for a first time duration of a clock cycle. The first NSCWV signal comprises a first base voltage and a first frequency. The method further includes performing a first transition to change from the first NSCWV signal to a second NSCWV signal. The second NSCWV signal is generated for a second time duration of the clock cycle. The second NSCWV signal comprises a second base voltage and a second frequency. The method further includes performing a second transition to change from the second NSCWV signal back to the first NSCWV signal. The first transition and the second transition are repeated over the clock cycle.
