191 Analog Electronics 8.3 Consider the circuit shown below. (a) Find an expression for Vx in terms of V1 and V2. (b) Find an expression for Vo1 in terms of Vx. (c) Find an expression for Vo2 in terms of Vo1 and V3. (d) Combine the above for your final answer. That is, give Vo2 in terms of V1, V2 and V3. 8.4 In the op-amp circuit below, dtermine Vo vs. V1 and V2. 10 k + - V1 5 k 10 k 1 k 10 k Vo1 Vo2 + - 5 k 2 k V3 Vx + - 2 k 1 k V 2 Vo 10 k 1 k + - 1 k V 2 + - V 1 4 k

192 Chapter 8: Amplifiers and Operational Amplifiers 8.5 Consider the op-amp circuit shown below. First, find the val- ues of Rf and Ra such that V0 = -3V1 + 13V2. Then, using these values and given that V1 = 3V and V2 = 1V, find the cur- rent Io flowing into the op-amp. 8.6 Consider the Op-amp circuit shown below. The Op-amp is ideal and in its linear range. Find the expression fro Vo vs. Vi. Vo Rf 1 k 15 k Io 10 k + - + - V 2 V1 Ra Vo 1 k 2 k 5 k 3 k + - + - 5V Vi 4 k

193 Analog Electronics 8.7 The Op-amp in the circuit below is ideal (a) What is the name of this type of circuit. What is the general expression for Vo vs V+ and V- if the gain A of the op-amp is 100,000. (b) Determine Vo when: V1 = 1.1V and V2 = 1.0V (c) Determine Vo when: V1 = 1.0V and V2 = 1.1V 8.8 Consider the Op-amp circuit shown below. The Op-amps are ideal and in their linear range. Find the expression for Vo vs.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
