Tests with a n channel FET show that it has the iD vs vGS characteristic shown below with V1 = 2.95 V and I1 = 27.1 mA. When vGS = +V1, iD = I1. When vGS = −V1, iD = 0 mA. a. What is the value of ID0 for this FET? (Give your answer to 3 s. f. ) b. What is the value of gm for this FET? Number Units (Give your answer to 3 s. f. Hint: the units for gm are the same as for conductance.)
