WebMay 22, 2024 · BJT Biasing A BJT has two pn-junctions viz. emitter-base junction and collector-base junction. Application of proper DC voltage at the two junctions of the BJT is known as BJT or Transistor Biasing. When a transistor used as an amplifier, the emitter-base junction is forward biased and collector-base junction is reverse biased. WebThe circuit which provides transistor biasing is called as Biasing Circuit. Need for DC biasing If a signal of very small voltage is given to the input of BJT, it cannot be amplified. Because, for a BJT, to amplify a signal, two conditions have to be met. The input voltage should exceed cut-in voltage for the transistor to be ON.
