Find G m [dm] of a source-coupled pair with a current-mirror load with nonzero mismatch (Fig. 4.29b)

Question:

Find G_m[dm] of a source-coupled pair with a current-mirror load with nonzero mismatch (Fig. 4.29b) and show that it is approximately given by (4.184). Calculate the value of G_m[dm] using the following data:

Ts T2 т. T4 T3 2.0 0.95 1.05 0.9 &m (mA/V) 1.05 0.95 1.1 0.5 1.0 I. (M2) 1.0

Compare your answer with a SPICE simulation. Also, compare your answer to the result that would apply without mismatch?
