The Simulation Settings were AC Sweep, Start and End Frequencies at 1 kHz, and 1 data Point/Decade. Select PSpice-View Output File, click OK, and run the simulation. The AC ANALYSIS listing of Fig. 26.56 results. There is an exact match between the theoretical solution provided above and the computer analysis. Hybrid Equivalent Network—Output Impedance For the output impedance, the applied source VSIN is set to 0 V by replacing it with a direct 0-� connection. Then a 1-A current source is applied as shown in Fig. 26.57. The ISRC current source was selected because it FIG. 26.56 Output file for the voltage across the load resistor of Fig. 26.55.

1184 ⏐⏐⏐ SYSTEM ANALYSIS: AN INTRODUCTION has the arrow in the symbol. Everything else in the network remains the same, so there is no need to rebuild the entire network. Simply make the changes and run the simulation. Even the simulation does not have to be changed since the chosen parameters will remain the same. The current source was given a magnitude of 1 A so that the magnitude of the VPRINT1 voltage would also be the magnitude of the output impedance. The results of Fig. 26.58 indicate an output impedance of 200 k�. The following theoretical analysis reveals that the output impedance is indeed 200 k�: Zo � � 1 1 �� 6 �200 k� 25 � 10 5 � 10 S �6 S � 20 � 10 �6 1 ———— 25 � 10 S �6 (4 � 10 S �� 1 k� � 1 —— 4 h h )( 50) o � � rhf � � hi � Rs � 0 FIG. 26.58 Output file for the voltage across the 1-A current source (and output impedance) of the network of Fig. 26.57.
