这种稳定方法的一个不足是：输入端的有关电压噪声和失调电压增大会额外地增加输出噪声和失调电压。
One disadvantage of this method of stabilization is the additional output noise and offset voltage caused by increased amplification of input-referred voltage noise and input offset voltage.
在版图的设计上，对输入级采用交叉耦合结构，减小由于工艺原理引起的MOS管匹配，从而减小电路的失调电压；
In layout design, the cross-couple structure is adopted in the input stage to minimize the MOSFET mismatch due to process, and consequently to lower the offset voltage in the circuits.
该转换器的高输入阻抗和低失调电压漂移输入增益级可以保证芯片在微弱电压信号下正常工作。
The designed converter could operate well with a slender supply voltage signal because of its high input resistance and low offset drift.
