    Simulated voltage gain in Multisim differs very much from calculated

    I tried different beta values, like 50, 100, 200, 300 via transistor parameter BF (Ideal maximum forward beta). But it doesn't change the results. I am using equations for common emitter amplifier from newly released book Electronic Circuits Fundamentals with MathCad Examples (author A-Imam...

    Simulated voltage gain in Multisim differs very much from calculated

    I am using Multisim software and I am comparing my calculated voltage gain with the one, done by Multisim. Why is calculated Av ( -478.8 mV) much different from the one in simulation ( -990 mV) ? I see the calculated is approx. half size of simulated. I tried using virtual transistor instead...
