Why does ce configuration provide large current amplification while the cb configuration does not?

The common emitter (CE) configuration provides large current amplification because it utilizes a small base current to control a much larger collector current, resulting in a significant current gain (β). In contrast, the common base (CB) configuration does not offer the same level of amplification since it is designed for high-frequency applications and has a lower input impedance, which leads to a smaller output current relative to the input. Additionally, the CB configuration does not allow for the same degree of control over the collector current by the base current as the CE configuration does.


Which of the transistor configuration is prefer?

It depends on what you want to do with the transistor. Class A, common emitter, is used for voltage amplification. Class C, common collector, is used for current amplification. There are other classes and configurations but, again, it depends on what you want to do.


Why more current amplification in common emitter?

A bipolar transistor can be used in different configurations in linear electronic design. Most well known is the common emitter CE configuration with a base current as input signal resulting in a collector signal multiplied by the current gain factor. The second configuration is known as the emitter follower or common collector configuration. Here the input signal is in the form of a voltage between the base and the common connection. The output signal is found in the form of a voltage at the emitter with a relative low output impedance. The voltage swing at the input is almost as large at the output where the input impedance equals the product of the current gain factor and the emitter resistance. The third configuration is known as common base CB. Here the input current at the emitter almost equals the output current at the collector. The current gain is nearly equal to 1.


What is the common transistor configuration used for signal amplifier?

Class A amplifiers for signals and class AB for power output. The bias is often set up as a self biased amp.


What is an operating point of dc load line?

Why can a PNP transistor be used as a power amplifier if it is connected into a circuit in a manner such as that shown in the book Electricity and Electronics Figure 52?

A PNP transistor can be used as a power amplifier in a circuit because it can handle high power levels and provide amplification by controlling a large current with a small input signal. In Figure 52, the PNP transistor is configured in a common emitter configuration, allowing it to amplify the input signal by controlling the current flowing through the load connected to its collector terminal. The transistor acts as a switch that modulates the output current based on the input signal, providing amplification of power.


Can you use CC configuration as an amplifier?

The Common Collector configuration amplifies current, by having the emitter voltage follow the base voltage, with an offset of the forward conduction voltage of about 0.7 volts, with a current gain of beta. (hFe)
