In a Half bridge MOSFET switching circuit, in order to prevent a "short" circuit through the high and low sides, I need to delay the turn on of the high/Low side until the Low/High side has turned off. I still need the switching speed to be as high as possible.
this is necessary because this is a very high speed switching circuit.
( a half bridge has current flowing from the positive supply through the High side through load to ground, and alternately from ground through the load and Low side to negative supply.)

Start with this: -
And then invert the output of the OR gate.
Both gates should be schmitt trigger types. The RC time constant and the schmitt trigger high and low thresholds produce the deadband timing.
