Sketch op-amp integrating circuit with waveform. Explain circuit operator in brief.

Obtained by replacing the feedback resistor $R_f$ in inverting amp configuration by “CF”. Assume that the op.amp used is ideal one.

$V_2→ \text{virtual ground potential.} \\ ∴kCL at V_2, \\ I_1=I_B+I_F--------(1) \\ \text{Due to high i/p impedence,} \\ I_B→∝,∴I_1≈I_f \\ \text{Now current through cap.} \\ I_c=C \frac{dV_c}{dt} \\ \text{But in …
