OP-AMP-এর ফিডব্যাক পাথে উপস্থিত একটি ক্যাপাসিটর এটিকে ইন্টিগ্রেটরের মতো কাজ করে।
ইনভার্টিং OP-AMP-এর স্থানান্তর করা হয়:
\({{V_o}(s)\over V_{in}(s)}=-{Z_2\over Z_1}\)
\({{V_o}(s)\over V_{in}(s)}=-{1/sC\over R_{in}}\)
\({{V_o}(s)\over V_{in}(s)}=-{1\over sR_{in}C}\)
∵ \({1\over s}=\int dt\)
\({{V_o}(t)}=-{1\over R_{in}C}\int{V_{in}(t)}\space dt\)
