Hi, KlausSt,
Sorry to tell you that my OSC signal is a square wave, about 1Hz. Do you think 100pF across R13 will work for such low freq oscillation?
I haven't try, just doubt it, OR should I increase 100pF? What is the limit for the capacitor across R13 that I can try?
Many thanks.

And, SunnySkyguy,
Since 16.5K+2.2uF may affect OpAmp output, so 1K+1UF(C7+R7) should affect AD8226 output more?
Thanks for your kindness.
