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。
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.
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。
Third, rail - to - rail amplifier output stages exhibit load - dependent gain which affects amplifier open - loop gain, and hence closed - loop gain accuracy.
运用一阶单时间常数低通函数模拟运算放大器的开环增益，对RC桥式振荡电路进行线性分析，得出最大振荡频率为运算放大器增益带宽积的16.67%。
The maximum frequency of RC-bridge oscillator is 16.67% of gain bandwidth product of amplifier analyzed based on a first-order single time constant lowpass function model.
