Transistor biasing ppt presentation12/9/2023 ![]() The maintenance of operating point stable is called Stabilisation. It is desired that once selected the operating point should remain stable. The circuit used for transistor biasing is called the biasing circuit.Ĥ BIAS STABILITY Through proper biasing, a desired quiescent operating point of the transistor amplifier in the active region (linear region) of the characteristics is obtained. The later method is more efficient and is frequently used. HOW A TRANSISTOR CAN BE BIASED? A transistor is biased either with the help of battery or associating a circuit with the transistor. ![]() WHY BIASING? If the transistor is not biased properly, it would work inefficiently and produce distortion in output signal. ![]() For faithful amplification it is essential that:- Emitter-Base junction is forward biased Collector- Base junction is reversed biased Proper zero signal collector current The proper flow of zero signal collector current and the maintenance of proper collector emitter voltage during the passage of signal is called transistor biasing. The process of raising the strength of weak signal without any change in its general shape is referred as faithful amplification. Presentation on theme: "TRANSISTOR BIASING & STABILIZATION."- Presentation transcript:Ģ Transistor Biasing The basic function of transistor is amplification.
