The device name and its model name are listed first.(6) This section provides detailed information about the solid state devices as requested by including the '.op' statement in the input file. **** OPERATING POINT INFORMATION TEMPERATURE = 27.000 DEG C (5) The next line gives the total power dissipation in the circuit. Thus, if the voltage source value is positive and the current is negative, then power is being delivered by the source. The convention is that positive current flows into the + node of the source, through the source, and leaves the - node. (4) The following section lists each voltage source by name, together with the dc current flowing through it. NODE VOLTAGE NODE VOLTAGE NODE VOLTAGE NODE VOLTAGE Also, the analysis can be repeated at a sequence of temperatures (see PSPICE reference). The temperature can be set to any value by including a.

When performing hand calculations of junction currents using exponentials, e.g., IC = IS(exp(VBE/VT), in order for your results to agree with PSPICE it might be necessary to use a value for the thermal voltage calculated with high precision. Also note that the default temperature is 27 C = 300.15 K.

(3) This section lists the dc voltage at each node in the circuit. **** SMALL SIGNAL BIAS SOLUTION TEMPERATURE = 27.000 DEG C These parameters are described in most PSPICE reference books. Some of these are obtained from the model statement(s) in the input file, others are calculated or default values. (2) Here are the values for the device models parameters used in the circuit. (1) PSPICE regurgitates the input file listing, annotated with the time and date:

The 'nopage' option suppresses page breaks in the output file.

Using meaningful text instead of numbers to label nodes makes the output easier to interpret.

Comments (lines beginning with *) can be inserted anywhere.
