Calculate the incremental slope of the transfer characteristic of the circuit of Fig. 5.8 at the quiescent point and at the extremes of the signal swing with v_i= v̂_isin ωt and v_̂i= 0.5 V:

a) Let A⁺_v = A_v when v_i is maximum.

b) Let A_vQ = A_v when v_i = 0.

c) Let A^€“_v = A_v when v_i is minimum.

Assume that V_I = 0, V_DD = 2.5V, I_Q =1 mA, and R_L†’ ˆž. Also, assume that (W/L)₁ = 1000, k' = 200 μ A/V², V_t0 = 0.7 V, Ï•_f = 0.3 V, and γ = 0.5 V^1/2.
