FAQs on Bipolar Transistor: Common Base Configuration Video Lecture - Analog and Digital Electronics - Electrical Engineering (EE)

1. What is the common base configuration of a bipolar transistor?
Ans. The common base configuration is one of the three basic configurations in which a bipolar transistor can be operated. In this configuration, the base terminal is common between the input and output, the emitter is the input terminal, and the collector is the output terminal.
2. What are the advantages of the common base configuration in electronics?
Ans. The common base configuration offers the following advantages: - High voltage gain: It provides a high voltage gain compared to other configurations, making it suitable for applications requiring amplification. - Low input impedance: It has a low input impedance, allowing it to easily interface with low impedance sources. - Good high-frequency response: It exhibits good high-frequency response due to its low input capacitance.
3. What are the limitations of the common base configuration in electronics?
Ans. The common base configuration has the following limitations: - Low current gain: It has a low current gain, which limits its use in applications requiring high current amplification. - Reduced power handling capability: It has reduced power handling capability compared to other configurations. - Inverted output phase: The output signal is inverted compared to the input signal, which may not be desirable in some applications.
4. How does the common base configuration differ from the common emitter configuration?
Ans. The common base configuration differs from the common emitter configuration in the following ways: - Input and output terminals: In the common base configuration, the input terminal is the emitter and the output terminal is the collector, while in the common emitter configuration, the input terminal is the base and the output terminal is the collector. - Voltage gain: The common base configuration has a higher voltage gain than the common emitter configuration. - Input and output phase relationship: The common base configuration provides an inverted output phase compared to the input, whereas the common emitter configuration provides a non-inverted output phase.
5. What are the typical applications of the common base configuration in electronics?
Ans. The common base configuration finds applications in the following areas: - High-frequency amplifiers: Due to its good high-frequency response, it is commonly used in high-frequency amplifiers. - Oscillators: It is utilized in oscillator circuits where frequency stability is important. - RF (Radio Frequency) circuits: It is employed in RF circuits for signal amplification and impedance matching purposes.
