电容负载往往会提高问题的困难度,其部分的原因是在于它们可以降低输出频宽以及回转率(slew rate),然而主要的原因还是因为它们在运算放大器的回授回路中所产生的相位延迟(phase lag)所造成的不稳定状态。虽然某
Capacitive loads tend to increase the difficulty of the problem in part because they reduce the output bandwidth and the slew rate, but mainly because of the phase delay they cause in the op amp’s feedback loop (phase lag) caused by the instability. Although some
