Question 2.25: PSpice Example Use PSpice to calculate the dissipated power ...

You have already learned how to set up the PSpice Schematic. You will discover some other useful PSpice functions in other chapters. In this example, you will learn how to use the current- controlled current source (CCCS) gain in the PSpice software. After gaining familiarity with CCCS, you will be able to easily apply the same procedure to voltage-controlled voltage source (VCVS), voltage-controlled current source (VCCS), and current-controlled voltage source (CCVS).

1. First, set up the PSpice Schematic as shown in Figure 2.89 .
2. Notice that there is an additional resistor with a very high resistance of 100 MΩ in the circuit. The reason for this is that an error will occur if the PSpice circuit is open. A high-resistance resistor is required and will act as a “bridge” to connect both sides of the circuit, while preventing any additional current flow through it.
3. To use the CCCS gain function in PSpice, go to “Place Part” and type “F.” Choose “F/Analog.”
4. After connecting the wires shown in Figure 2.89, double-click the F icon to open the schematic properties window shown in Figure 2.90.
5. Change the “GAIN” value from “1” to “5,” and then click the “Display…” that is located near the arrow in Figure 2.90 .
6. A “Display Properties” window will pop up as shown in Figure 2.91. In the “Display Format” section, choose to display “Name and Value,” then click OK.
7. Then the CCCS gain block will show “GAIN = 5” as shown in Figure 2.92.
8. Set up the simulation profile with “Analysis Type” as “Bias Point” and run the simulation. The simulation result is shown in Figure 2.92.
