Step of 5 13.061P In the analysis of the 741 second stage, the effect of placing appropriate resistors at the emitters of and is considered. The requirements are, 2 For the 741 operational amplifier the parameter values are, 550 = 22 mA/V Determine the small-signal input resistance between base and emitter looking into the base. (B+1) 8m = 22x10⁻³ Determine the output resistance. ro 50 = 550x10 Step of 5 Determine the output resistance at the transistor, Step of 5 Simplify further. 2.32Rg 0.348 0.808 0.808 1.972 = 0.4097 kΩ = 409.7 Step of 5 Consider the ratio, 550 = 730 550 730 Substitute 409.7 Ω for = 550 (409.7) Step of 5 Consider the ratio, 550 = 180 Substitute 409.7 Ω for 550 180 Thus, the resistance values in each of the emitters are, 308.9 Ω
