"NettetRamp generators are used to produce a sawtooth waveform. Ideally, the sawtooth waveform consists of a voltage which increases linearly with time until it reaches a predetermined final value, instantaneously returns to zero, and immediately increases again as the cycle repeats. One application of this waveform is to produce a linear time … " - Linear phase ramp
