Hello. I'm currently doing some work relate to BGV.

I'm trying to use the switch M10 to control the current flow from M1 to Q0.

However, when the switch from on to off and from off to on, the current is very large and it affect a lot.

I would like to know what can i do to reduce this effect.
 

A slower gate drive rise/fall time will make a shorter
(but wider) edge overshoot. Applying realistic loading
(C) will soak up some of the gate charge. Using no
larger than necessary switch devices cuts gate charge
proportionally. Driving the gate no further than necessary
also can cut gate charge injection.
 
Try a capacitor (MOSCAP) of ≈100fF in parallel to Q0 .
