Question: Repeat Problem 4.14, but now assuming that 2 k¦ resistors are inserted in series with the sources of M 3 and M 4 . Ignore

Repeat Problem 4.14, but now assuming that 2 k„¦ resistors are inserted in series with the sources of M3and M4. Ignore the body effect?


Repeat Problem 4.14:

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 μΑ -VSUP

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