Analysis를 수행하여 slew rate을 구하라.
⇒ slew-rate 는 단위시간당 출력전압의 최대변화량을 말합니다. 증가하는 범위에서의 기울기가 slew-rate 이다. 여기서는 13.857 / 32.088us = 0.4318 V/us 가나온다.

Slew Rate을 측정하라. AC전원의 주파수는 10KHz이다.
AC 전원의 주파수를 1KHz로 낮추고 OP Amp의 출력전압이 10VPP가 되도록 조정하여 OP Amp의 대역폭(Bandwidth)을 결정하라. 대역폭은 주파수의 증가에 따라 출력신호를 관측하여 slew-rate 찌그러짐이 발생

slew-rate 때문에 그 출력을 따라가지 못하고, 더 작은 전압을 출력한다. 그 원인인 slew-rate를 측정한다.
