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.

设计了一个测量放大器电路，它由差动放大电路、共模抑制电路、双端单端转换电路和程控增益放大电路组成。

A measurement amplifier circuit is designed, which consists of circuits of differential amplifier, a common-mode rejection, double-end and single-end conversions and programmed gain amplifier.

电路见图5，这种电路在运算电路中相当有用，比如差分对单端的转换，抑制共模信号。

This circuit is shown in Figure 5 and is useful as a computational amplifier, in making a differential to single-ended conversion or in rejecting a common mode signal.
