Question

A transistor has a current amplification factor of 60. In a ce amplifier, input resistance is 1kohm and output voltage is 0.01v. The tranceconductance is?

Answer 1

Given that,

The current amplification factor of a transistor is 60

In a ce amplifier, input resistance, $R_i=1\ k\Omega$

Output voltage, $V_o=0.01\ V$

To find,

The tranceconductance of the amplifier.

Solution,

The ratio of change in collector current to the change in emitter voltage is called tranceconductance. Its formula can be given by :

$g=\dfrac{\beta}{R_i}\\\\g=\dfrac{60}{10^3}\\\\g=0.06$

So, the tranceconductance of the transistor is 0.06.
