Question
Why is the linear portion of the triode characteristic chosen to operate the triode as an amplifier?
Advertisements
Solution
When the operating point lies on the linear portion of the characteristics curve, change in voltage across the load resistance follows the pattern of the input signal, but the amplitude is much larger. This can be done by choosing the linear portion of triode characteristic.
