Nodes 2, 0, and 6 in basic circuit will be assigned to nodes 10, 20, and 30 in the subcircuit, respectively. 2. General format for Voltage controlled voltage source is: Ename N1 N2 NC1 NC2 Value In the example, it is specified with positive node 30, negative node 0 while nodes 20 and 10 being the possitive and negative nodes of the controling volatge. The value of the controlling constant is 5E4. Requiremnt: Change the input file such that the two inputs are not synchronized. This can be achieved by changing TD of the pulse from 0 to 0.1ms and run the program again. Figure 5: SPICE file for the adder circuit You must have your SPICE output file with your hand calculations ready before you come to the lab. EXPERIMENTAL WORK See pin configurations of 741 op amp in the data sheet given in the Appendix at the end of the manual. Also, note when testing the adder and difference circuits that the two input are not synchronized and hence be careful when you plot the results. 1. Construct the voltage buffer circuit shown in Figure 1. Apply a sine wave of 1V and frequency of 1kHz. Monitor the input and output wave forms and sketch the output in Table I. 2. Repeat step 1 for the inverting amplifier. 3. Construct the adder circuit. In this case, two inputs are need. Generate the triangular signal normally from the function generator whereas use its SYNC output to provide the square wave input. Note that square wave varies from 0 to 5V and its amplitude cannot be changed. Sketch the output in Table I. Be careful when you plot the results the two inputs may not be synchronized. 4. Construct the inverting integrator. Apply a square wave normally from the signal generator of 1V and frequency of 1kHz. Monitor the input and output wave forms and sketch the output in Table I. 5. Test your design of the prelab and sketch the output in Table I 34
35 6. Construct the differentiator circuit. Apply a triangular wave of 1V and frequency of 1kHz. Monitor the input and output wave forms and sketch the output in Table I. 7. Repeat step 3 for the difference amplifier. 8. Test your design of the prelab and sketch the output in Table I. 9. Construct the voltage to current converter circuit. Apply a sine wave of 1V and frequency of 1kHz. Since the oscilloscope can not be use to measure current, measure the amplitude of the voltage V out for the two cases Z L =1kΩ and Z L =2kΩ. Then calculate I out in each case. Record your results in Table I. 10. Comment on your results.
