Abstract
A linear voltage-to-duty cycle converter is disclosed in which an input voltage to be converted is transformed to a triangle wave signal which has up and down ramps whose slopes are variable with the input voltage. A hysteresis comparator receives the triangle wave signal and produces a resulting output signal that has either a high value or a low value depending on the triangle wave signal condition. The time the resultant output signal is high or low compared to the overall time constitutes a duty cycle that is linear with respect to changes in the input voltage.
