Why the shape of the output characteristics curve for common emitter circuit are not equally spaced?

It is a non-linear device.


Why base in grounded in common emitter transistor as amplifier?

With a common emitter amplifier it's the emitter that is usually grounded.


What are the characteristics of a common emitter amplifier?

There are a number of characteristics found in a common emitter amplifier. Not only are the parameters considered, but also their performance. Characteristics and performance are: voltage gain/ medium; current gain/ medium; power gain/ high; input / output phase relationship/ 180 degrees; input resistance/ medium; and output resistance/ medium.


What are different names of CE amplifier?

In a common emitter transistor the primary purpose of a resistor connected to the emitter is to?

The emitter resistor in a common emitter configuration provides negative feedback to the transistor, reducing both its voltage gain and distortion.


What is the effect on voltage gain in a common emitter amplifier when the decoupling capacitor is removed?

The emitter bypass capacitor, in a typical common emitter configuration, increases gain as a function of frequency, making a high pass filter. Removing the capacitor will remove the gain component due to frequency, and the amplifier will degrade to its DC characteristics.


How does using a transistor with a different beta affect the operation of the common emitter amplifier?

Gain, in the common emitter amplifier, is beta (hFe) or collector resistance divided by emitter resistance, whichever is less. Substituting a different beta (hFe) transistor will affect gain, if hFe is less, or increase stability and design margin, if hFe is greater.


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.


What do you mean by common emitter configuration and biasing pnp transistors?

A common emitter BJT transistor has the emitter ground. So u measure input voltage at base with respect to the ground, i.e; emitter and also u measure the output voltage at collector with respect to the ground, i.e; emitter. Hence, the emitter is common and thus the name.


What is the relationship between common base and common collector?

It all depends which lead is connected to the common power supply, Emitter, base or collector. For most amplification needs using NPN transistors, common emitter is used. Other applications are used for current control and regulation circuits.

Why is collector current increased slowly with the increase of collector to emitter voltage of a common emitter?

The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.
