In the circuit of an Op-Amp as an integrator, the feedback circuit mainly contains a ______.
Capacitor
An ideal Integrator circuit is shown below:
It is clear from the circuit diagram of the integrator, the feedback element is a Capacitor .
Note:
At high frequencies, the capacitor is a short circuit so the output is 0.
At low frequencies, the capacitor is an open circuit, the output voltage is the amplified input voltage(the output is non-zero).
thus an ideal integrator acts as a low pass filter.
Important Points
The feedback path in an op-amp differentiator consists of a resistor.
At high frequencies, the capacitor is a short circuit so the output is the amplified input voltage(the output is non-zero)
At low frequencies, the capacitor is an open circuit, the output voltage is 0.
thus an ideal Differentiator acts as a High pass filter.
