ABSTRACT:
A ramp generator has a capacitor connected via a resistor to charge toward 2-volts on the clock lead. The other side of the capacitor is connected to a voltage divider between the control voltage input and ground, to give the initial value of the ramp, which determines the pulse width output. The ramp output is connected to the set input of a D type flip-flop, whose output is the desired pulse width. Another flip-flop is toggled by each clock pulse, to control the alternating selection of two output gates. Three diodes in series from the clock lead to the ramp conductor, across the capacitor, and then to ground are used to reset the ramp when each clock pulse goes to ground potential.
