Can spike voltage transient at input gates during control signals switching be avoid?
If these spikes are near or &lt; 30ns, they are false probe errors from long inductive ground connectors and probe ground length. 

$$ V=L dI/dt $$ and transistor turn off (dt) times can be very fast then air coupled RF inductive crosstalk begins. 

Turn on DSO 20MHz to suppress or fix with short connections 1cm with twisted pairs if long.
