    This paper analyzes that the low input resistor of the gated integrator will result in the charge loss when the signal ends and the switch is still turned on. An impedance conversion circuit based on a common base amplifier is presented to solve this problem. In the electronic test and the application in ICF experiments it has been proved that this method can decrease the charge loss.
