From the given transfer characteristic of a transistor in CE configuration, the value of power gain of this configuration is 10 x , for R B = 10 kΩ , and R C = 1 kΩ . The value of x is _____.

Step-by-step solution

The formula to calculate the current gain β in CE configuration is given by β = ∆ I C ∆ I B       . . . 1 Considering the third and the first points on the given graph, the current gain can be calculated as follows: β = 30 - 10 × 10 - 3   A 300 - 100 × 10 - 6   A =   100 The formula to calculate the power gain P in CE mode can be written as P = β 2 · R C R B       . . . 2 Substitute the known values of the parameters into eq
