Chapter 1, Problem 40P Step- by-step solution Step Calculate the voltage gain v, Substitute 2.2 V for and 0.2 V for v, in the 2.2 V 0.2 V Therefore, the voltage gain, is 11 V/V Calculate the voltage gain in decibels Substitute 11 V/V for in the equation. 20.827 Therefore, the voltage gain, in decibels is 20.827 dB Step Calculate the output current 2.2 100 = 22 mA Calculate the current gain i, Substitute 22 mA for and mA for i, in the 22 mA 1 mA Therefore, the current gain, is 22 A/A Calculate the current gain in Substitute 22 A/A for in the dB Therefore, the current gain in decibels, is Step Calculate the power gain. Substitute 11 V/V for A, and 22 A/A for A, in the W/W the power gain, is 242 W/W Calculate the power gain in decibels Substitute 242 W/W for A2 in the =10(2.3838) Therefore, the power gain, in decibels is 23.838 dB Step of 6 Calculate the power supplied by DC sources =0.12 W Therefore, the power, P& supplied by the dc sources is 0.12 W Calculate the input power. 0.2 mW Step Calculate the Power delivered to the 48.4 mW 2 Calculate the Power dissipated in the amplifier circuit Pdissipated Therefore, the power dissipated, Pdissipated in the amplifier circuit 95.9 mW Comments (4) Anonymous why are they being divided by sqrt 2? Anonymous ^to get rms value which the value of ac that highly same as dc value Anonymous to convert from AC PK to RMS DC Anonymous as we are adding numbers by the DC power supply, all values must also be DC Step of 6 Calculate the amplifier efficiency Substitute 24.2 mW for and 0.12 W for in the equation. (100%) 0.12 W =(0.20167)(100%) Therefore, the amplifier efficiency, 20.167%
