That is not always true. The fraction of the charge that is placed on
the signal line during the time that the impedance of the transistor
is still low can be caused to flow to the ground by the existance of
the resistance in series.
Only if it bangs an ESD diode. And Marra specified a "low value
resistance" A series R can help if the injected charge is driving an
opamp nuts, by reducing peak current, but it won't reduce the charge
kicked into a capacitor, barring the esd diode thing.
This is a way that the size of the hold step in a sample and hold
circuit can be reduced at the cost of spreading out the acquire time.
The amount of reduction in charge can be quite a bit if the gate must
move a long way before the device starts to turn off.
I don't understand that. Where do the electrons go?
