Figure Q3(a) shows the schematic diagram of an ideal op-amp integrator circuit, which simulates mathematical integration by determining the total area under the curve of a function. A square wave as shown in Figure Q3(b) is applied to the input of the differentiator. (1) The integrator has CF = 1 nF and R₁ = 10 k. Determine the output voltage V. at time t=0 s, t=2 μs, t=5 μs, t= 10 μs. (ii) At low frequencies, the ideal integrator circuit may become unstable and drive the output signal into saturation. Explain why. (iii) Suggest a modification to the ideal integrator circuit to eliminate the instability. Vi (V) R₁ V₁M + CF HH Figure Q3(a) V₂ 10 02 10 5 Figure Q3(b) t (us)
