其优点是可以减少使用运算放大器、电容以及开关的数量，使得SCF面积减小，便于小型化。

The advantage of the new method is that the number of ICOA, capacitor and switch and the area of SCF are all decreased.

对于便携式电子产品来说，运算放大器可算是万能的信号调节电路，因为它可以执行滤波器、放大器、电压感测器、电平移位器、缓冲器、甚至开关等多种不同功能。

Operational amplifier is the most versatile signal conditioning block in any portable system. It can be a filter, an amplifier, an voltage detector, a level shifter, a buffer or even a switch.
