The above is quoted from here and I have build the circuit in LT Spice for simulation. The output (highlighted in pink) is as expected that is complementary PWM. However, the question is how do I actually position the wave so that it has same amount of dead time between both waves because it seems that from the picture the waveform is shifted to one side only and not in middle? LT Spice file is below for download :)

Thank you :)

There are many chips available that are specifically designed to do exactly what You want,
and allow You to set the dead-time with a simple Resistor, and/or, Capacitor selection from a graph.
