SUMMARY
The voltage gain calculation for a 2-stage amplifier involves determining the gain for each stage using the formula Ao (Gain) = - Rf/R1. The first stage yields a gain of -1.5, while the second stage results in a gain of -1.55. The overall voltage gain is calculated by multiplying the gains of both stages, resulting in a positive gain of 2.34. For accurate results, it is essential to multiply the voltage gains for each stage rather than adding them, unless converting to decibels.
