高频阻抗变换器在纳秒门控积分器中的应用

High-frequency impedance conversion circuit for a gated integrator

叙述了一种利用共基极放大电路构成的高频阻抗变换器。将这个电路应用到纳秒级门控积分器中 ,能有效地减低门控积分器前端的电荷泄漏 。

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.
