Description : State the need of biasing and describe the concept of DC load line
Answer : Need of Biasing for Transistor: The transistor should be biased in the active region if it is to be used for amplification and in saturation and cut off if it is used as a switch. 2. The Q ... The position of operating point on the load line is dependent on the application of the transistor.
Description : Define: i) Q point ii) DC loadline iii) Need of biasing iv) Current gain
Answer : i) Q point: It is the point on the load line which represents the dc current through a transistor (ICQ) and the voltage across it (VCEQ), when no ac signal is applied. ii) DC load line: The ... region is as desired. iv) Current Gain: It is a ratio of output current to input current.
Description : State the need of biasing of BJT.
Answer : Need of biasing: The basic need of transistor biasing is to keep the base-emitter (B-E) junction properly forward biased and the collector-emitter (C-E) junction properly reverse biased ... transistor biasing is necessary for normal and proper operation of transistor to be used for amplification.
