The figure below shows a feedback amplifier constructed using an nMOS transistor. Assume that $\mu_{\mathrm{n}} \mathrm{C}_{\mathrm{ox}}=1 \mathrm{~mA} / \mathrm{V}^2$, threshold voltage $\mathrm{V}_{\mathrm{T}}=1 \mathrm{~V}$ and $\mathrm{W} / \mathrm{L}=2$. The bias voltage at the drain terminal is $4 \mathrm{~V}$. The capacitors $\mathrm{C}_{\infty}$ offer zero impedance at the signal frequency. The ratio $\mathrm{V}_{\text {out }} / \mathrm{V}_{\text {in }}$ is___________ (rounded off to two decimal places).
