Question:

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 $C=0.1 \mu \mathrm{F}$.
image text in transcribed (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 $t$ ?
