用单位增益缓冲器构成的开关电容滤波器（SCF），若能消除寄生电容引起的“阻性”寄生，则可用于高频设计，总寄生灵敏度会因此大大降低。
The unity gain buffer will be good for designing high frequency SCF if its resistive effect can be eliminated and then the overall parasitic sensitivity will be greatly lowered.
由于共振增强多光子电离（REMPI）母体离子谱与碎片离子谱的相似性，可用探测总离子信号的方法来替代单独的母离子探测，有效地提高痕量探测的灵敏度。
Similarities in the REMPI spectra of all the ions could lead to greater trace detection sensitivity if the total ion yield is concerned instead of only the parent ions.
所以输出电压可以用来度量输入电流，总的灵敏度由反馈电阻器（RF）决定。
Thus, the output voltage is a measure of input current, and overall sensitivity is determined by the feedback resistor RF).
