5. Fill in the blanks in the paragraph:
When acting as amplifiers, BJTs are operating in (1) mode, wherethe EBJ is (2) and the CBJ is (3).
For small signals, a BJT functions as a linear (4), therefore DCbias is required in amplifier designs, in which we need toestablish a DC collector current that is (5) the value of beta.
The (6) amplifier is used to obtain the bulk of the requiredvoltage gain in a cascade amplifier. It has large voltage gain,moderate input resistance, and relatively (7) output resistance. Ifa resistor is put in series with its emitter, the (8) of theamplifier can be increased at the expense of a decrease in (9),which is also called (10) resistance.
The (11) amplifier has very low input resistance and has anexcellent high-frequency response.
The (12) amplifier is also called an emitter follower and has ahigh (13) and low output resistance. An important application ofthe emitter follower is the (14) of a cascade amplifier.
