由于OP本身的开环路增益(open loop gain)很大，所以非反向输入端的电压会反射到反向输入端，使得反向输入端的直流电位也变成Vref；而OP输出端的直流电位为非反向输入端的...

This design is the use of leading correction principle, finally meet the performance index of a control system open loop gain, phase margin, angular frequency requirements.
本设计利用超前校正原理，最终满足对控制系统性能指标开环放大系数、相角裕量、截止角频率的要求。
As shown in Figure 2-9, the guard buffer significantly reduces the charging time of CSHUNT because of the open-loop gain (AGUARD), which is typically 104 to 106.
如图2 - 9所示，由于保护缓冲放大器具有典型值为104到106的开环增益，所以能够大大减少CSHUNT的充电时间。
Third, rail - to - rail amplifier output stages exhibit load - dependent gain which affects amplifier open - loop gain, and hence closed - loop gain accuracy.
第三，轨到轨放大器输出级增益与负载有关，这将影响放大器的开环增益，当然也影响了闭环增益的准确性。
