What is the effect of emitter resistance in common emitter amplifier?
The gain of a common-emitter amplifier is collector resistor divided by emitter resistor, or hFe, whichever is less. Since hFe depends on temperature, designing the amplifier to be dependent on resistance ratio makes it more stable. As such, the emitter resistance serves to stabilize the amplifier.
Why we use emitter resistance in circuits?
The emitter resistor is connected to ground(in the case of an rc coupled amplifier).Also input signal applied at the base is grounded.Then the emitter resistor forms a feedback to the input signal (through the ground return path).So emitter resistor is also called feedback resistor.
What are the major advantages of Emitter-coupled logic?
Ilv
What is the other name for the common-collector amplifier?
emitter follwer
What are the steps involved in finding the signal gain for a common-emitter BJT amplifier?
The signal gain of a CE BJT amplifier is hFe or collector resistance divided by emitter resistance, whichever is less.
What happens if you remove emitter resistor in RCcoupled amplifier?
what happens if we remove Rc in RC coupled amplifier
Why output of common emitter amplifier is inverted?
In a common emitter amplifier, the base-emitter current causes a corresponding collector-emitter current, in the ratio of hFe (beta gain) or collector resistance over emitter resistance, which ever is less. Since this ratio is usually greater than one, the differential collector current is greater than the differential base current. This results in amplification of the base signal. As you increase the base-emitter current, the collector-emitter current also increases. This results in the collector being pulled towards the emitter, with the result that the differential collector voltage decreases. This results in inversion of the base signal.
Why base in grounded in common emitter transistor as amplifier?
With a common emitter amplifier it's the emitter that is usually grounded.

What is the difference between a CB amplifier and CE and emitter-follower?
I think you mean a common emitter amplifier, which is an amplifier of voltage. Emitter-follower or common collector amplifiers are used to match impedances, or to amplify power or current. The emitter-follower is a type of common emitter circuit that has a resistor between the emitter and ground. The output signal is taken from the point between the emitter and its resistor.
Which amplifier has largest bandwidth?
Direct coupled amplifier
What are different names of CE amplifier?
what is the other name of common emitter amplifier
How does emitter coupled logic works?
In electronics, emitter-coupled logic, or ECL, is a logic family in which current is steered through bipolar transistors to prevent saturation.
What are the major advantages of Emitter-coupled logic?
Ilv
What configuration commonly employed in bipolar transistor amplifier?
Common Emitter - Class A Amplifier.
