This design is the use of leading correction principle, finally meet the performance index of a control system openloopgain, 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-loopgain (AGUARD), which is typically 104 to 106.
Third, rail - to - rail amplifier output stages exhibit load - dependent gain which affects amplifier open - loopgain, and hence closed - loop gain accuracy.
