What is the current gain of common collector configuration?
The common collector configuration has a voltage gain of about “1” (unity gain). Thus it can considered as a voltage-buffer since the voltage gain is unity.
What is the current gain for common base transistor?
0.98
In a common base transistor circuit, the current gain is 0.98.
What is current gain for CE transistor configuration?
Current gain in the common emitter circuit is obtained from the base and the collector circuit currents. Because a very small change in base current produces a large change in collector current, the current gain (β) is always greater than unity for the common-emitter circuit, a typical value is about 50.
What is a common collector configuration?
Definition: The configuration in which the collector is common between emitter and base is known as CC configuration. The collector is common to both the input and output circuit and hence the name common collector connection or common collector configuration. …

What is the current gain for a common-base configuration where is 4.2 mA and IC 4.0 mA?
What is the current gain for a common-base configuration where IE = 4.2 mA and IC = 4.0 mA? Correct answer is between ‘0.95,0.96’.
What is the current gain of a common-base amplifier?
Common-base transistor amplifiers are so-called because the input and output voltage points share the base lead of the transistor in common with each other, not considering any power supplies. The current gain of a common-base amplifier is always less than 1.
What is current gain of common-base amplifier?
The current gain of a common-base amplifier is always less than 1. The voltage gain is a function of input and output resistances, and also the internal resistance of the emitter-base junction, which is subject to change with variations in DC bias voltage.
What are the different configurations of transistors with respect to gain?
The behavior of these three different configurations of transistors with respect to gain is given below. Common Base (CB) Configuration: no current gain but voltage gain. Common Collector (CC) Configuration: current gain but no voltage gain. Common Emitter (CE) Configuration: current gain and voltage gain.
What is the value of collector current in a transistor?
The value of collector current depends on base current and leakage current along with the current amplification factor of that transistor in use. This configuration provides voltage gain but no current gain. Being VCB constant, with a small increase in the Emitter-base voltage V EB, Emitter current IE gets increased.
What is the power gain of a common collector amplifier?
It has low voltage gain and high current gain. The power gain of the common collector amplifier is medium. To fully describe the behavior of a transistor with CC configuration, we need two set of characteristics – input characteristics and output characteristics.
What is the voltage gain provided by CC configuration?
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.
