Transistor Biasing : Types of Biasing, Advantages & Disadvantages

WebWhy is biasing used in transistor amplifiers? Transistor biasing makes analog and digital operation of a transistor possible. Without transistor biasing, BJT amplifiers fail to deliver the required output across load terminals. The optimum value of transistor bias voltage is equal to two times the required AC output voltage peak. Web1.Fixed bias (base bias): The single power source (for example, a battery) is used for both collector and base of a transistor, although separate batteries can also be used. In the given circuit, Vcc = IbRb + Vbe. Therefore, IB = (Vcc − Vbe)/Rb. For a given transistor, Vbe does not vary significantly during use.
