For the given circuit, Aspect ratio of $$M_{1}$$, transistor is $$\frac{20}{0.5}, I_{D_{1}} = 200 \mu A, V_{THO} = 0.6 V, 2 \phi_f = 0.81 V, \gamma = 0.4 V^{2}$$ and $$\mu_{n} C_{ox} = 59.5 \mu A/V^2$$. If $$V_{in} = 1.2 V$$, find the minimum value of aspect ratio of $$M_{2}$$ transistor to ramin saturated $$(\sqrt{10} = 3.16)$$
