Advanced Transfer formulas for Voltage Controlled Current sources

A Voltage Controlled Current source (G1) injects a current into the base of Q1. Notice that the transfer equation for the G1 is a complex equation involving power, ln and e. The PSpice Master’s Class covers how to generate these complex equations using regression software, and conversion of the result to a PSpice recognizable syntax.

 

Building a complex transfer function that incorporates several individual component curves.

These waveforms illustrate how to build a complex transfer function that include several, more simple transfer functions. This methodology can be used to create ‘calibration curves’ for corrections to the transfer function of your circuit, or can be used to simplify the building of more complex effects of your circuit, such as temperature effects and non-linear I-V relationships. The PSpice Master’s class covers how to go through this process, and end up with one G element in your schematic, with a complex mathematical transfer function that simulates quickly.

 

Interface Technologies’ PSpice Master’s Class is a custom configured advanced PSpice training class. We have been developing presentations on advanced areas of PSpice for over 20 years, and now offer these training modules in two flexible formats:

  1. “Ala carte” selection of subjects to be covered as an add-on day(s) to our two day on-site class
  2. Complete coverage of advanced subjects during our PSpice Master’s Class

The benefits of The PSpice Master’s Class include the following:

  • Clear and logical presentation of subject matter – compiled from scattered source documentation
  • Hands-on, interactive labs solidify the presentation with ‘real software’ experience
  • Introduction to little known or poorly documented features and uses of PSpice
  • Better understanding of PSpice component modeling

The Master’s class is conducted twice a year, as a two day ‘extension’ of the Introduction to PSpice with Schematic Capture class. It builds upon the fundamental skills learned in the Introduction class and pulls the user to a higher level of competence.

On-site Classes

The PSpice Master’s class, or portions of it, can be brought to your location and conducted on-site.

Typically, a discussion with the person coordinating the training will identify the subjects of particular interest. We’ll discuss what we need to cover in the Introductory class, and the elements of the Master’s class that are pertinent to the students. Once that is done, we’ll know the amount of time that the class will take, and the number of students. Then we can send a formal quote for the class.

This class, and portions of it, have been taught on 3 continents, and all across North America.

2017 Schedule for the PSpice Master’s Class

Classes are held twice annually in the United States. The cost for the two day Introduction to PSpice with OrCad Capture class is $1795/student, and includes the two days of training, lunch each day, an student copy of the PSpice software, and a certificate of achievement. The additional two days for the PSpice Master’s Class is $2100 per student.  Students should sign up for 4 days of training, at $3895. per student.

If you want to attend the Master’s class only (the last two days, for $2100), please contact me, Dan Waterloo, so that we can go over the prerequisite skills.
