Consider the op-amp circuit shown below, where R1 = 2, R3 10, R4 = 4, and R2 you need to select yourself. In the circuit, ii is a DC current source with your own selected value, and is the AC voltage source with frequency and amplitude of your choice.

Instructions

R,
1. Calculate v. theoretically. 2. Simulate the circuit and compare the experimental v theoretical. 3.Set up the experiments and calculate gain(s) using measurements from the graph of the simulations (make sure that all required voltages and currents are displayed on the
graph and the values used in calculations are shown on the graph).
4. Set up the experiments and calculate input resistance(s) using measurements from the graph of the simulation (make sure that all required voltages and currents are displayed on the graph and the values used in calculations are shown on the graph).
I. Your submission should include one Multisim circuit file and one graph file with required number of graphs (one graph for each experiment). All graphs should be labeled with the type of experiment and clearly display important simulation parameters. 2. For the Opamp use OPAMP_3T_VIRTUAL from Analog/ANALOGyIRTUAL 3. The OPAMP in Multisim is a model of a real opamp, and may display unexpected behavior if the voltages and currents are beyond certain limits. To have results similar to what you would expect from an ideal opamp that we use for theoretical calculations, you may need to: a) use smaller values for voltage and current sources and/or b) use the values of resistors that would provide reasonably small currents and/or c) make the op-amp “more ideal” by increasing the supply voltage and by increasing the gain.
