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 offsetvoltage in the circuits.
One disadvantage of this method of stabilization is the additional output noise and offsetvoltage caused by increased amplification of input-referred voltage noise and inputoffsetvoltage.
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。

The designed converter could operate well with a slender supply voltage signal because of its high input resistance and low offset drift.
