Find the short-circuit transconductance of the super-source follower shown in Fig. 3.43. Assume I 1 = 200
Question:
Find the short-circuit transconductance of the super-source follower shown in Fig. 3.43. Assume I1 = 200 µA, I2 = 100 µA, W1= 30 µm, and W2= 10 µm. Also, assume that both transistors operate in the active region, and ignore the body effect. Use the transistor parameters in Table 2.4. Assume Ldrwn= 0.40 µm and Xd= 0.1 µm for all transistors.
