Derive and sketch the complete small-signal equivalent circuit for a bipolar transistor at I C = 0

Question:

Derive and sketch the complete small-signal equivalent circuit for a bipolar transistor at I_C = 0.2 mA, V_CB = 3V, V_CS = 4 V. Device parameters are C_je₀ = 20 fF, C_μ₀ = 10 fF, C_cs₀ = 20 fF, β₀ = 100, τ_F= 15 ps, η = 10⁻³, r_b = 200 Ω, r_c = 100 Ω, r_ex = 4Ω , and r_μ = 5β₀r_o. Assume ψ₀ = 0.55 V for all junctions.
