Vedclass · Answer

(D) In a common emitter $(CE)$ amplifier configuration,the transistor must be operated in the active region. For the active region,the base-emitter junction must be forward-biased,and the collector-base junction must be reverse-biased. Therefore,statement $(a)$ is correct. Furthermore,in a $CE$ amplifier,the input signal is applied to the base-emitter circuit,which is in series with the $DC$ bias voltage applied to the base-emitter junction. Therefore,statement $(c)$ is also correct. Thus,both $(a)$ and $(c)$ are correct.
