FAQs on Common Collector Configuration Video Lecture - Analog and Digital Electronics - Electrical Engineering (EE)

1. What is a common collector configuration in electrical engineering?
Ans. A common collector configuration, also known as an emitter follower, is a type of bipolar junction transistor (BJT) circuit where the emitter terminal is common between the input and output.
2. What is the purpose of using a common collector configuration in a circuit?
Ans. The common collector configuration is often used to provide impedance matching between the input and output of a circuit, as well as to provide voltage gain close to unity.
3. How does a common collector configuration differ from a common emitter configuration?
Ans. In a common emitter configuration, the input signal is applied to the base terminal and the output is taken from the collector terminal, while in a common collector configuration, the input signal is applied to the base terminal and the output is taken from the emitter terminal.
4. What are the advantages of using a common collector configuration in amplifier circuits?
Ans. Some advantages of using a common collector configuration include high input impedance, low output impedance, good current gain, and high voltage gain close to unity.
5. Can a common collector configuration be used as a voltage buffer in electronic circuits?
Ans. Yes, the common collector configuration, due to its high input impedance and low output impedance, is commonly used as a voltage buffer to isolate the input and output of a circuit while maintaining the signal voltage level.
