Mell Which transistor configuration produce high current gain and high voltage gain?
common emitter amplifier configuration
The Common Emitter (CE) Configuration The common emitter amplifier configuration produces the highest current and power gain of all the three bipolar transistor configurations.
Which transistor configuration is used for both voltage and current amplification?
Common emitter transistor configuration
Common emitter transistor configuration Both current and voltage gain can be described as medium, but the output is the inverse of the input, i.e. 180° phase change. This provides a good overall performance and as such it is often the most widely used configuration.
What is 3 configuration transistor?
The three types of configurations are Common Base, Common Emitter and Common Collector configurations. In every configuration, the emitter junction is forward biased and the collector junction is reverse biased.
Which configuration of BJT amplifier has highest current gain?
Which configuration of BJT is mostly preferred Why? Thus CE configuration is best for amplification because of its high power gain (due to its both high voltage and current gain) and hence most widely used.
Which amplifier configuration is best?
If CC configuration is considered for amplification, though CC amplifier has better input impedance and lower output impedance than CE amplifier, the voltage gain of CC is very less which limits its applications to impedance matching only.
What is the gain of a common base transistor?
Now we discuss about the above three transistor configuration s with diagrams. The common base transistor configuration gives a low i/p while giving a high o/p impedance. When the voltage of the CB transistor is high, the gain of the current and overall gain of the power is also low compared to the other transistor configurations.
Which is the most common configuration in a transistor?
The common emitter is the configuration in which both current and the voltage gains are present. Hence the common emitter is the most widely used configurations. As the name suggests the configuration is of the common terminal base this remains common for both the input and the output circuit connections.
What are the features of a phase transistor?
Although the voltage is high, the current gain is low and the overall power gain is also low when compared to the other transistor configurations available. The other salient feature of this configuration is that the input and output are in phase.
How does a CC configuration work in a transistor?
In CC configuration, the input resistance is high and the output resistance is low. The voltage gain provided by this circuit is less than 1. The sum of collector current and base current equals emitter current. The input and output signals are in phase. This configuration works as non-inverting amplifier output.
