What is Transistor Biasing? Circuit Diagram & Types (Fixed Bias, Collector to Base Bias, Voltage Divider Bias)
For the transistor to act as an amplifier is must be operated in its active region. The method of applying external voltages to operate the transistor in the active region is known as Transistor Biasing. For achieving a perfect amplification in amplifier circuit proper biasing is needed.

What is Voltage Follower using Op-Amp? Circuit Diagram, Derivation & Working
The circuit in which output voltage is exactly equal and in-phase with its input, then the circuit is known as voltage follower.
A non-inverting amplifier, whose gain is equal to 1, acts as a voltage follower. The circuit includes an op-amp and a wire connecting the output and input terminals. A non- inverting amplifier configured as voltage follower is illustrated in figure below.
