The Transfer Function analysis (DC small signal analysis) calculates the DC input resistance, DC output resistance and DC gain.
Description
Enter a brief description of the type of analysis. The text entered is the title of the document in which the simulation results will be stored.
Input Source
The small signal input source used as the input reference for the calculations.
Output
Specify the output variable that can indicate a voltage or a current flowing through an independent voltage source. The box lists all the voltage generators (in the form I(source_name) where I indicates the current flowing in the source) and all the nodes of the circuit. Select the name of a source or the name of a node. If the name of a node is selected, the voltage of that node referred to the ground node (GND) will be considered. To specify a voltage between two nodes, select the second node in the box on the right.

In order to be able to easily refer to the circuit nodes, it is advisable to assign a name to the connections directly in the schematic. To assign a name to a connection, you must hook a Net Label object on a wire belonging to the connection. |
Temperature
Specify the temperature at which the simulation will be performed.
Analysis Mode
Specify whether a single or multiple analysis should be performed. The multiple analysis performs several consecutive simulations, varying the value of some parameters at each step. When a multiple analysis is selected, the Setup button is activated. Click on the button to activate the dialog in which to set the specific parameters for the selected analysis mode.
The following analysis modes are supported, click a link to learn more about that analysis mode:
Options
Click on this button to activate the dialog box in which to set the options of the simulator. The options set are only valid for the current analysis and replace those defined in the general tab of the simulator options.
