amplifier has a gain of unity andVcc= 25Vdc, RL= 8Ω and Vi(p-p)= 34V.a. Calculate the input power, the output powerand the efficiency of the amplifier.b. Consider the operation mode that the two output transistors dissipate the maximum power. For this operation mode, find the output voltage across the load and the power dissipated by each transistor.
A resistive load of 4 ohms is matched to the collector impedance of an amplifier by means of a transformer having a turn ratio of 40:1. The amplifier uses a DC supply voltage of 12V in the absence of input signal. When signal is present at the base, the collector voltage swings between 22V and 2V, while the collector current swings between 0.9A and 0.05A.
Determine: (a) the collector impedance
(b) Signal power output
(c) DC power input
(d) Collector efficiency
