Industrial Strength Simulation




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.




Current-limited Power Supply Model


Ever wanted to make a power supply that was current limited? Here is an easy way to generate a current-limited voltage source.
Current-Limited Supply
The source is implemented with an NTIOFV source. This source has its voltage controlled by the current flowing through its input terminals according to a tabular list. You control the degree of current limiting by constructing the appropriate current, voltage data pairs in the table. Here is a plot of the output voltage versus the input current. Notice that it exactly matches the values specified in the TABLE attribute.
