读数偏置可能由输入放大器过载或输入端的直流整流效应所引起。

A reading offset may be caused by input amplifier overload or DC rectification at the input.

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。

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

没有反馈电阻的仪表放大器提供精确增益，无论增益多大，放大器的同向和反向输入端提供高输入阻抗。

An instrumentation amplifier offers precise gain without feedback resistors, and, at any value of gain, it provides high input impedances at its noninverting and inverting inputs.
