The inverting OP AMP in Figure P7-21 is driven by a step input \(v_{\mathrm{S}}(t)=2 u(t)\). Let \(R_{1}=2 \mathrm{k} \Omega, R_{2}=20 \mathrm{k} \Omega\), and \(C=0.1 \mu \mathrm{F}\).
(a) If \(v_{\mathrm{C}}(0)=8 \mathrm{~V}\), find \(v_{2}(t)\) for \(t \geq 0\).
(b) What is the value of \(t\) when \(v_{2}(t)=0 \mathrm{~V}\) ?
(c) Does the OP AMP saturate? If so, at what value of \(t\) ?
(d) Validate your answers using Multisim.
R +M Vs(1) Vc(0) + ww R -o+ V(1) Vcc= 15 V
