Question: Repeat Problem 4.12 except replace Q 1 and Q 2 with n-channel MOS transistors M 1 and M 2 . Also, replace Q 3 and
Repeat Problem 4.12:
Determine the unloaded voltage gain νo/νi and output resistance for the circuit of Fig. 4.58. Check with SPICE and also use SPICE to plot out the large-signal VO-VI transfer characteristic for VSUP = 2.5 V. Use SPICE to determine the CMRR if the current-source output resistance is 1 M¦.
Figure 4.58:

+VSUP Q3 v,= Vo+v Q2 V = V, + v; 100 -VSUP
