Question

Question 1 : Determine the voltage gain of the amplifier shown in Figure 1.

μ_n C_ox (W/L)= μ_p C_ox (W/L)=1 mA/V² ,|V_t|=2 V, R₁=R₂=10 MΩ, R_S=1KΩ, R_L=10 KΩ and V_DD=V_SS=4 V.

Question 2 : Determine the voltage gain of the amplifier shown in Figure 2.

Assume g_m=2 mA/V,R₁=R₂=30 k and V_A=45 V.
