Repeat Problem 4.12 except replace Q₁and Q₂with n-channel MOS transistors M₁and M₂. Also, replace Q₃and Q₄with p-channel MOS transistors M₃and M₄. Assume W_n= 50[1]m and W_p= 100 µm.

Repeat Problem 4.12:

Determine the unloaded voltage gain ν_o/ν_i and output resistance for the circuit of Fig. 4.58. Check with SPICE and also use SPICE to plot out the large-signal V_O-V_I transfer characteristic for V_SUP = 2.5 V. Use SPICE to determine the CMRR if the current-source output resistance is 1 M„¦.
