Redesign the feedback circuit in given figure using mosfets

Question

Redesign the feedback circuit in given Figure using MOSFETs to provide a voltage gain of A_{v f} = 8 and such that v_o = 0 when v_i = 0.

Assume circuit parameters of R_S = 1 k Ω, R₁ = 15 k Ω, and R_L = 10 k Ω.

The transistor parameters are  = 100μA/V², V_TN = 1.5 V, and λ = 0.
