Question

For a common base amplifier, if the values of voltage gain and resistance gain are 2800 and 3000 respectively, find the current gain and power gain of this amplifier.

Solution

Given,
Voltage gain = 2800
Resistance gain = 3000

Therefore,

Current gain, $α = \frac{voltage gain}{resistance gain}$

$\Rightarrow$ $α = \frac{2800}{3000} = 0.93$

$Power gain = \frac{(voltage gain)^{2}}{resistance gain}$

$= \frac{(2800)^{2}}{3000} = 2613.3$
