- The figure below shows an inverting amplifier connected to a load RL. Determine the power gain of the amplifier. power gain for the amplifier, G, is defined as the power ratio that reaches the load RL versus the power supplied by the source VS.4) Below is the small signal model of a multistage amplifier. Using this model, write the equationsthat you would need to determine the voltagegain. IMPORTANT: You only need to providethe equations that you would need to determinethe voltage gain. You DO NOT need to combine and simplify the equationsto determine a final expression for the voltagegain.
