Assignment-2) Consider the same long n-channel MOSFET above, but now biased with V_GS = 2.5 V, V_DS = 4 V, and V_BS = 0 V. Estimate the sheet charge density in the inversion layer at the source and drain ends of the channel. Estimate the current flowing through the drain of this transistor. Use m_e = 500 cm²/V-s.
