CE Amplifier
Description:
- C1 is known as Cin. It passes all AC signal and block DC signal
- R1 & R2 is potential divider bias which provide excellent stability so Q point doesn't change because of temperature voltage etc.
- R3 is known as Rc. It will vary with input voltage changes.
- R4 is known as Re. Which is use as thermal runaway. That protects transistor from damaging.
- C3 is known as Ce. And also known as Bypass capacitor because resistor Re decreases the gain of Amplifier but after use of Bypass capacitor 'Ce' then AC signal will become sort-circuited and it will increase the gain of CE amplifier.
