News:

Spectrum Software has released Micro-Cap 11, the eleventh generation of our SPICE circuit simulator.

For users of previous Micro-Cap versions, check out the new features available in the latest version. For those of you who are new to Micro-Cap, take our features tour to see what Micro-Cap has to offer.

Models

 

I have created a circuit that contains an opamp. The opamp is only being used for its gain capability so I have no need for all of the other modelling capabilities of it such as slew rate limiting, saturation, offset, etc. How can I change the opamp model so it is an ideal opamp?

 

Double click on the opamp while in Select mode to invoke its Attribute dialog box. In this dialog box, highlight the MODEL attribute by clicking on that line in the list window. When this attribute is highlighted, and a name has been defined for the attribute, the parameter fields at the bottom of the Attribute dialog box will become active and available for editing. Changing the Level parameter to a value of 1 will model an ideal opamp. The only parameters that are used with the Level 1 opamp are the A, ROUTAC, and ROUTDC. This model level is represented by a current source and a resistor.
