![]() ![]() ![]() It defines where the transistor will operate on its characteristics curves under dc conditions. What is operating point? Why is it necessary to stabilize operating point of a transistor amplifier?Īns. The zero signal values of I C and V CE are known as the operating point. For linear amplification (amplification with minimum distortion), the operating point should not be too close to the maximum power, voltage, or current rating besides avoiding the regions of cutoff and saturation.Īns. The process of raising the strength of a weak signal without any change in its general shape is referred to as faithful amplification.Ĥ. The operating point defines where the transistor will operate on its characteristics curves under dc conditions. It is also known as quiescent point or Q point. It is called operating point because the variations of I C and V CE take place about this point when signal is applied. What is operating point? Explain its physical significance.Īns. The zero signal values of I C and V CE are known as the operating point. It may be noted that transistor biasing is very essential for the proper operation of transistor in any circuit.Ģ. The circuit used for transistor biasing is called the biasing circuit. The latter method is more efficient and is frequently used. ![]() A transistor is biased either with the help of battery or associating a circuit with the transistor. If the transistor is not biased properly, it would work inefficiently and produce distortion in the output signal. Ans. The proper flow of zero signal collector current and the maintenance of proper collector-emitter voltage during the passage of signal is called the transistor biasing. ![]()
