2. Pulse Generator
Rev.1.00 Mar 10, 2006 page 10 of 15
The charge and discharge circuits in the circuit from figure 1 are separated by diodes in this circuit. (See figure 3.)
This allows the pulse width and the duty cycle to be set independently. Figure 4 shows the waveforms generated by
this circuit.
