Th
culation of �32.74° of Example 18.4. Now this solution is fine for the
ac signal, but it tells us nothing about the dc component.
By exiting the SCHEMATIC1 screen, we obtain the Orcad Capture
window on which PSpice can be selected followed by View Output
File. The result is the printout of Fig. 18.99 which has both the dc
and the ac solutions. The SMALL SIGNAL BIAS SOLUTION includes
the nodes of the network and their dc levels. The node numbers
are defined under the netlist starting on line 30. In particular, note the
dc level of 3.6 V at node N00676 which is at the top of resistor R 3 in
Fig. 18.97. Also note that the dc level of both ends of the inductor is the
same value because of the substitution of a short-circuit equivalent for
the inductor for dc analysis. The ac solution appears under the AC
ANALYSIS heading as 2.06 V at �32.66°, which again is a great verification
of the results of Example 18.4.
