Unformatted text preview: Ae/APh 104a Homework Problem Set #5 ISSUED: Thursday, November 11, 2010 DUE: Thursday, November 18, 2010 (in class) 1/4 Basic opamp circuits By finding expressions for the output in each case, determine the functions of the following opamp circuits: (a) (b) 1 (c) The diode on the inverting input has the currentvoltage relationship i = e v , where and are constants. 2/4 Real opamp behavior Figure 1: voltage follower Consider the voltage follower shown above. (a) By analyzing various configurations of the schematic test circuit shown in the figure below, find expressions for the following real parameters of the opamp in terms of A,R i ,R o and R L (the resistance on the output of the opamp): (i) the open loop gain, A , where A v oc v test , and v oc is the voltage at the output when R L = 0, i.e. an open circuit; 2 Figure 2: Schematic for question 2 (ii) the effective input resistance, R i , where R i v test i test ....
