Draw the transfer characteristic curve of a base biased transistor in CE configuration. Explain clearly how the active region of the `V_0` versus `V_F` curve in a transistor is used as an amplifier.

Text Solution

Verified by Experts


In the active region, a (small) increase of `V_i` results in a large, almost linear) increase in` I_c` This results in an increase in the voltage drop across `R_c`
