An n-channel MOSFET has \( t_{ox} = 20 \, nm \), \( \mu_n = 650 \, cm^2/V \cdot s \), \( V_t = 0.8 \, V \), \( \frac{W}{L} = 10 \).

\[
\epsilon_{ox} = 3.9 \times 8.85 \times 10^{-12} \, F/m; \quad C_{ox} = \frac{\epsilon_{ox}}{t_{ox}}; \quad I_D = \frac{1}{2} \mu_n C_{ox} \frac{W}{L} (V_{GS} - V_t)^2
\]

Determine the drain current and operation mode for the following cases:
a) \( V_{GS} = 5 \, V \), \( V_{DS} = 1 \, V \)

b) \( V_{GS} = 2 \, V \), \( V_{DS} = 1.2 \, V \)

c) \( V_{GS} = 5 \, V \), \( V_{DS} = -0.2 \, V \)

d) \( V_{GS} = 5 \, V \), \( V_{DS} = 5 \, V \)
