Thus, the output voltage, V is the derivative of the input voltage V and the

multiplying factor is (– CR).
17.6.4 Op-amp As an Integrator
In an integrator, the output voltage is proportional to the integration of the
input voltage with respect to time
From Fig. 17.7 (b),

Again V = Aυ

or,
If A → α, v → 0.
The point Q of which potential is v tends to zero.
Assuming υ = 0
