ELEC 380 Electronic Circuits IITutorial and Simulations for Micro-Cap IVByAdam Zielinski(Posted at: http://wwwece.uvic.ca/~adam/)Version: August 22, 2002ELEC 380 Electronic Circuits II - Tutorial 1-1TUTORIALThis manual is written for Micro-Cap IV - Electronic Circuit Analysis Programfor Macintosh computers. The PC Version of the program is available at:www.spectrum-soft.com. Prior to proceeding please familiarize yourself withthe Simulation Tutorial for ELEC 330 posted at:http://www.ece.uvic.ca/~adam/. In this Tutorial we will explore otherinteresting features of the Micro-Cap IV that are relevant to the material coveredin the class. The simulations #1 to #6 are part of preparation to the laboratorysessions and must be completed before the laboratory and obtained presented tothe laboratory instructor.1. AC AnalysisThe AC analysis allows us to see a frequency response or AC transfer functionH(jω) of a linear circuit. You can imagine that a sinusoidal voltage source withamplitude 1 volt is applied to a specified node of a circuit (input) and thatvoltage and relative phase is measured at a different specified node (output) ofthe same circuit. The voltage ratio or voltage gain and relative phase shiftbetween these two voltages depend on frequency applied. The gain (oftenexpressed in decibels or dBs) and phase are plotted vs. frequency over thespecified frequency range. Frequency often is displayed in logarithmic scale. Insuch scale distance ...
