Q1. an amplifier operating from ± 3 v supplies provides a 2.2 v peak sine wave across a 100 ω load when provided with a 0.2 v peak input from which 1.0 ma peak is drawn. the average current in each supply is measured to be 20 ma. find the voltage gain, current gain and power gain as ratios and in decibels. (10 points) q 2. the input and output voltages of an amplifier are v i = 5 sin ( 1000 π t + 30 ∘ )mv and v o = 400 sin ( 1000 π t + 90 ∘ )mv. find the magnitude and phase of the voltage gain of the amplifier.
