Abstract
Systems and methods for generating digital waveforms with high-resolution duty cycles are disclosed. A smoothed sinusoidal waveform set to a voltage other than ground may be generated and/or received. A rectangular waveform may be generated based on the sinusoidal waveform using a comparator. The rectangular waveform may be utilized to adjust the duty cycle of a current applied to a mass analyzer to improve duty-cycle resolution of a mass analyzer of a mass spectrometer.
