I designed the BJT amplifier below. After substituting in for the values of the actual resistances measured in lab, I reran the simulation. The hand calculation I derived for the gain was nearly spot on with what I was seeing in Multisim. Now, when in lab I get approximately the same value I should. The only issue is that I seem to have some sort of increasing DC bias on the output. The output will first start out at around 2.11V and slowly creep up until around 3V. What can I do to avoid this problem? I thought perhaps by adding a larger capacitance, but it did not change much.
