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.
A sexy transistor are two type. NPN and PNP..... c means common b means base .
The base is excited by a very low current. That turns the transistor on so that a higher amount of current flow comes out.
Common base connection.
common emitter using fixed bias
The emitter resistor in a common emitter configuration provides negative feedback to the transistor, reducing both its voltage gain and distortion.
The pin configuration of sl 100 is B C E with ground as the base of the transistor.
Common Emitter Configuration has maximum impedance.
because in ce configuration value of input voltage requried to make the transistor on is very less value of the output voltage or output current
A sexy transistor are two type. NPN and PNP..... c means common b means base .
there are 3 types of configuratons......they are 1.common emmiter configuration 2.common collector configuration 3.common base configuration
Common Emitter - Class A Amplifier.
The base is excited by a very low current. That turns the transistor on so that a higher amount of current flow comes out.
In an NPN transistor an emiter follower refers to an amplifier topology. The emiter follower configuration is when the emitter of a N-Type Bipolar Junction Transistor (BJT) is connected to the common point on a circuit (typically ground). This is not always the case, however, because many amplifier configuration exist.
Common base connection.
common emitter configuration is use for amplification purpose while common collector is use as buffer as its op is same as ip..
Common Emitter(CE) Configuration possess largest voltage gain among the three(CE CB CC).
output current is zero
