What is Biasing? Essential Condition For Biasing

Transistor biasing

The transistor biasing is done in order to keep
Biasing Circuit

  • The faithful amplification of transistor amplifier circuit is done by biasing circuit and this is provided by placing bias battery ( DC voltage ) at the input side of the transistor. 
  • The circuit which provides transistor biasing is called as transistor biasing circuit.

Essential condition for biasing circuit
The following conditions must be necessary in order to faithful amplification.
Biasing Methods
  • Base resistor method
  • Emitter bias method
  • Collector feedback resistor bias method
  • Voltage divider ( Universal bias ) method
