What is the operating point of the amplifier?

Hello friends, once again all of you are welcome to electric guider, today in this article I am going to tell you that what is the operating point of the amplifier?, What is the operating point of an amplifier called. so let’s start

What is the operating point of the amplifier?

Biasing is used to achieve a fixed state of current and voltage. This fixed condition of current and voltage is called the operating point or operating point.  You must have known that what is the operating point in amplifier, if you want to know more information about it, then keep reading this article completely.

For the linear function of the transistor, the transistor should always operate in the active region, so the operating point or Qpoint should always be located in the active region. To fix the Q point, the voltage and current to be applied must be also proper. So that the Q point can neither shift in the saturation region nor the cut-off region.

In both these regions, the transistor shows nonlinearity, so it does not exactly reproduce the input signal in the output.

transistor amplifier in CE configuration. have been shown. output characteristics for the same configuration. Following are the types. This output characteristic shows the relationship between collector current (Ic) and collector-emitter voltage (Vor) for different base currents such as Ib=0, IBI, Ib2.
