This added voltage is mainly power line frequency and its effect on the voltmeter reading will depend upon the normal-mode rejection capability of the meter.

这个相加的电压主要为电源频率的信号，其对于电压表读数的影响决定于电压表的串模抑制能力。

The piecewise corrected current generator also forms negative feedback to improve the line regulation and power supply rejection(PSR).

该分段线性电流产生电路还形成了一个负反馈，以改善带隙基准源的电源抑制和线性调整率。
