UNIVERSITY OF CALIFORNIA AT BERKELEY College of Engineering Dept. of Electrical Engineering and Computer Sciences Problem Set #7 Due Tuesday, March 21 st , 2006. EE 105 Spring 2006 1) a. v out = R L R L + R out 10 v i and v i = R in R S + R in v in " v out = R L R L + R out R in R S + R in 10 v i " v out / v i = 10 R L R L + R out R in R S + R in = 2.5 V / V b. Remember that i out is defined as the small signal current entering the port, and thus the minus sign is needed above. i out / v in = " 10 R L + R out R in R S + R in = " 250 μ S c. i out = " 10 v i R L + R out = " 10 i in R in R L + R out # i out / i in = " 10
