Answer to Question #284890 in Electrical Engineering for H K

Question

(1) There are two PN junctions in a bipolar transistor. Each one can be either forward 

biased (FB) or reverse biased (RB). In the reverse active mode of operation, how 

are these two junctions biased? ( ). 

A. Emitter-base is FB and base-collector is FB. 

B. Emitter-base is FB and base-collector is RB. 

C. Emitter-base is RB and base-collector is FB. 

D. Emitter-base is RB and base-collector is RB. 

(2) In a good bipolar transistor operating in the active region, what is the spatial profile 

of minority carriers in the base? ( ). 

A. Exponentially increasing from emitter to collector. 

B. Exponentially decreasing from emitter to collector. 

C. Linearly increasing from emitter to collector. 

D. Linearly decreasing from emitter to collector.
