关于运放的基本问题

如图所示，双端输入单端输出的运放，Vout本身就不为0，怎么定义它的vout=0的点？

If you use the opamp to build a unity gain buffer, for nominal Vin, Vout should be equal to Vin. You can define this Vout as "Vout = 0". It will never be 0 V if you use single power supply. But if you have dual power supply, i.e., +5V for VCC and -5V for VSS, Vout can be 0 V.
