For Circuit 1 break the feedback loop open just to the right of the feedback network and for Circuit 2 break the loop open just to the left of the feedback network to find for each circuit: a.) The Loop Gain, L b.) The Percent Gain Error, E % . 2. For circuits 3 and 4 above break open the feedback loops “inside the Op Amp” model to find: a.) The Loop Gain,

Unformatted text preview: L b.) The Percent Gain Error, E % . 3. Use the OP Amp model in the file HW#4_Op_Amp_Model with V CC = +15V and V EE = -15V to construct Circuit 1 in Multisim7. Open the feedback loop at the same place as was done in 1a.and insert a 1kHz E T voltage source and a Z D resistor with the value computed in 1a. With this setup use simulated measurements to determine the numerical value of the Loop Gain, L . Express your answer to 4 digits. ( Note: Don’t forget to turn off E s when determining L .)...
