Physics - Semiconductors Question with Solution | TestHub

Given:

AC current gain, $\beta =65$

Load resistance, $R_L=5400\Omega$

Input resistance, $R_{in}=450\Omega$

The voltage gain $A_v$ of a common emitter amplifier is given by:

$A_v=\beta \times \frac{R_L}{R_{in}}$

Substituting the given values:

$A_v=65\times \frac{5400}{450}$

$A_v=65\times 12$

$A_v=780$

Answer: $780$
