***no need to compare to simple source follower*** The amplifier shown in Fig. 12.90 provides a closed-loop gain close to unity but a very low output impedance. Assuming λ > 0, determine the closed-loop gain and out- put impedance and compare the results with those of a simple source follower VDD M5 Vout Figure 12.90
