Hi Zewei,
the LF357 is a decompensated OPAmp and is much faster than the OPA172.

Hello Zewei.
The AC gain looks like 1M/100 = 10,000. It would be better to get this gain in two stages.
The input is small and the edges are steep. Try a faster op amp.
Hi Zewei,
what is the input signal (amplitude, offset, timing)? What is the supply voltage?
