Above is quoted from here. This circuit produces beautiful rain drop led. May I know how do I actually increase the deadtime which means all led are off for a longer period for all the 4 led as shown above? My LT Spice file is below. Thank you :)

I've added parameters to control the clock signal.
Change DC param to whatever duty cycle you wish to use.

.param DC= 0.1 (% decimal, 1=100%, 0.1=10%, etc.)
