For the common-source amplifier of Fig. 3.12, calculate the small-signal voltage gain and the bias values of V_iand V_oat the edge of the triode region. Also calculate the bias values of V_iand V_owhere the small-signal voltage gain is unity with the transistor operating in the active region. What is the maximum voltage gain of this stage? Assume V_DD= 3V, R_D= 5 k „¦, μ_nC_ox= 200 μA/V², W = 10μm, L = 1μm, V_t= 0.6V, and λ = 0. Check your answer with SPICE.
