Unformatted text preview: EE3115 Discussion 10 04/16/09 Problem 2 In the circuit below, a µA741 op amp is used where the current needed to operate the op amp is a few mA . The threshold voltage Vt is 5.1 V and 4.9 V for the output voltage of 14.6 V and -14.6 V, respectively . Vt is the voltage drop through R2 . a) Calculate R1 , R2 and R3 . b) Calculate the current flowing through R1 and R2 when R3 is very large . c) Calculate the current flowing through R1 and R2 when R3 is 1 MΏ . d) Sketch the transfer characteristic with the values of R1 and R2 in question c) . ...
