Other Parts Discussed in Thread: LF353,
我想模拟反相运算放大器，求证增益为10的时候，对应的Gain bandwidth的频率限制（-3dB点）为多少，我搜到Gain bandwidth 是4MHz，那么十倍增益对应带宽应该是400MHz，我实验验证也差不多这个值。但是模拟的时候发现17dB点对应的带宽是300KHz左右，和实际不符合，想知道我哪里出问题了，是我放大器增益带宽设置有问题吗，这个在哪设置。
I want to simulate an inverting op-amp, and I want to find out what is the frequency limit (-3dB point) of the corresponding Gain bandwidth when the gain is 10.
I found that the Gain bandwidth is 4MHz, so the bandwidth of 10 times gain should be 400MHz, and I experimented and verified that it is about the same value.
But when I simulated it, I found that the bandwidth of 17dB point is about 300KHz, which is different from the actual one.
