ELC10009 Worksheet 10 (Chapter 14 Hambley's Book) P 14.5 The input voltages of a differential amplifier are v,(t) = 0.5 cos(2000rt) +20 cos(120mt) and v2 (t)-0.5 cos(2000mt) + 20 cos(120mt) Find the expression for the common-mode and differential components of the input signal. Answer: Víd(t) = cos(2000t) and vicm(t) 20 cos(120t) P 14.10 In the ideal inverting op-amp is shown in figure, Un-3 sin(2000mt), R1 = 12 kn, R2-24 k Vin a) Find the output voltage as a function of time vo (t) b) Find the vin and vo and the current through each resistor and the output current of the op-amp just before the feedback loop begins), at t1.25 s. c) Sketch vin (t) and vo(t) to scale versus time Answer: a) vo(t) =6 sin(2000), b) vin-3 V, Vo6 V, 11 = 0.2 m1A, 12-0.2 mA, 106 mA, i,--6.2 mA c) P 14.xx Find all labeled currents and the output voltage for the ideal op-amp shown in figure. Take R, - 5 kQ, R2-15 kQ, R1 = 2 k & vm = 10 V. Also, find the voltage gain? R2 i R Vin t% RI Answer
