Q&A How to avoid shoot-through in MOSFET bridge drivers

I'm using a variable duty cycle square-wave oscillator to drive a half-bridge MOSFET pair like this. Upper MOSFET is P-channel type, lower MOSFET is N-channel type: - And, I think I'm getting shoo...

And, I think I'm getting shoot-through current pulses. Is there a simple way to resolve this?
