amplifier provides a voltage gain of 20 and a current gain of 35. Find its power gain

You are required to design an inverting amplifier, based on an op-amp with an open-loop gain which varies in magnitude with frequency as shown in the graph below. Your amplifier must operate at a frequency of 100 kHz. What value for the open-loop gain should you use to design the amplifier? click here for image O dB 100 1000 Infinity 10 120 100 80 60 40 20 0 100 101 Magnitude of Open-loop gain vs Frequency 10² 10³ Frequency (Hz) 104 105 106 G

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.
