Question

Difference between small signal and large signal analysis

Answer 1

Answer:

Explanation:

A small signal model accounts for the behaviour which is linear around an operating point. When the signal is large in amplitude (Say more than 1/5 VCC, a rule of thumb) the behaviour became non linear and we have to use the model which accounts for non linearity. And thus called large signal model....

Answer 2

The small signal model accounts for the behavior which is linear around an operating point. When the signal is large in amplitude (say more than 1/5 of VCC, a rule of thumb) the behavior becomes non linear and we have to use the model which accounts for non-linearity , and thus called large signal model.
