Which is the output current of CB configuration?
In the common base configuration, the collector current IC is the output current, and the emitter current IE is the input current. Thus, the ratio of change in emitter current to the collector at constant collector-base voltage is known as a current amplification factor of a transistor in common base configuration.
What are the input and output impedances of CB configuration?
What are the input and output impedances of CB configuration? Ans:The input impedence is VEB/IE and output impedence is VCB/IC . 15.
What is emitter base and collector?
The base is the gate controller device for the larger electrical supply. The collector is the larger electrical supply, and the emitter is the outlet for that supply. By sending varying levels of current from the base, the amount of current flowing through the gate from the collector may be regulated.
What are output characteristics?
Output Characteristics: This is a plot of output current versus output voltage with constant input current. Current Transfer Characteristics: This characteristic curve shows the variation of output current in accordance with the input current, keeping output voltage constant.
What is input and output characteristics?
Input Characteristics: The curve describes the changes in the values of input current with respect to the values of input voltage keeping the output voltage constant. Output Characteristics: The curve is got by plotting the output current against output voltage keeping the input current constant.
What is the difference between collector and emitter?
The main differences between emitter and collector are doping concentration and size. The emitter is heavily doped, while the collector is lightly doped. You could try to swap them, but you’ll get a very low HFE, probably even less than 1.
What does Collector do in transistor?
The collector-base junction is always in reverse bias. Its main function is to remove the majority charges from its junction with the base. The collector section of the transistor is moderately doped, but larger in size so that it can collect most of the charge carrier supplied by the emitter.
What is the difference between common emitter and common collector?
Common Emitter Configuration – has both Current and Voltage Gain. Common Collector Configuration – has Current Gain but no Voltage Gain.
What is the difference between a common collector to an emitter follower amplifier?
The main difference between the two will be where the output is taken. For the common emitter amplifier, we will take the output at the collector of the transistor. For the emitter follower, the output will be taken at the emitter of the transistor.
