最后，所述集成电路包括一第一电压电平控制器，所述第一电压电平控制器设置成在所述第一及至少第二电流馈电电路上分离对所述npn晶体管进行编程所需的电压。

Finally the integrated circuit has a first voltage level controller provided to split the voltage needed to program the NPN-transistor over the first and at least second current feeding circuit.

为了保证低泄漏电流和低介电吸收，反馈电容器应当由合适的介电材料(如聚苯乙烯、聚丙烯或聚四氟乙烯)制成。

To ensure low leakage current and low dielectric absorption, the feed back capacitor should be made of a suitable dielectric material such as poly styrene, polypropylene, or Teflon.

如第2.3.2节所述，电容器的容抗随着频率的增加而降低，这就会增加反馈电流表的增益。

As discussed in Section 2.3.2, the decreasing reactance of the capacitor with increasing frequency will increase the gain of the feedback ammeter.
