Characteristics of a Common Emitter (CE) Amplifier

(1)             Its input resistance is less up to a specific limit (1K to 2K)

(2)             Its output resistance is high up to a proper limit (50K or above)

(3)             Its current gain (B) is high (50 to 300 times)

(4)             Its voltage gain is very high (1500 or more)

(5)             It produces a big power gain (10,0000 times or 40 db)

(6)             It produces “Phase Reversal” of input signal. It means that input signal and output signal are produced at a difference of 180 degree to each other.
