Equipment designers can minimize the effects of these mismatches or "unbalances" through judicious choices of input and output stage circuit topologies and common-mode impedances.

设备设计师能通过审慎地选择输入输出级电路的拓扑和共模阻抗来最小化失配或“非平衡”的效应。

Any common-mode current (ICM) that may be present flows from the voltmeter input lo to instrument chassis common, through earth ground to voltage source ground.

可能出现的共模电流(ICM)从电压表的输入低端流到仪器的机箱公共端，经过大地再流到电压源的地。

Again, consider using AMPLIFIERs that exhibit a smooth input bias current transition throughout the applied input common-mode voltage.

再者，所用的放大器也要考虑在加到输入端的整个共模电压(范围内)输入偏置电流转换保持平滑。
