What is the Purpose of dc biasing in transistors?
in order to establish the Q-point of transistor
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
What is difference between transistor biasing and connection?
Transistor biasing is a function of implementing a DC support circuit that places the transistor in an electrical region that produces the desired output signal in relation to its input signal, according to its design specification. A transistor can be biased to create a linear amplified signal proportional to its input. Biasing can also place the transistor into an easily saturated condition to propagate clipped binary output relative to its input. Biasing refers to the component configuration designed around a specific transistor family. Connection refers to the simple function of making an electrical junction between two conductors.
State the various methods of coupling of transister amplifier?
Biasing the transistor so that it remains into the linear range is one way the other way is to couple one stage to another via a capacitor to remove extra biasing DC voltage therefore remaining into the linear range
How do you choose q point on load line?
the fixed amount of current and voltages are developed across the transistor is called biasing. thus the fixed voltages and current developed are called Q-point
What is the Purpose of dc biasing in transistors?
in order to establish the Q-point of transistor
What is effect of emitter resistor?
It provide sufficient biasing to the transistor. ANSWER: It purpose is to provide bias and limiting gain.
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
In which transistor bias method is the input signal rectified?
in which of the following transistor bias methods is the input singel rectified? A. source biasing b.voltage divider biasing c.power supply biasing d.avc biasing

What is self biasing a transistor?
if a transistor resistor is connected to the emmiter .
What are the biasing roles of transistor?
A: Transistor to be effective as an linear amplifier it must be operated in its linear load range. The biasing scheme is to insure that the transistor is put in its linear/load range
What is emitter biasing?
Emitter biasing is when you add a resistor between the emitter of a transistor and the 0v rail so that any voltage developed across the emitter will subtract from the voltage on the base and effectively turn the transistor OFF. We are talking about an NPN transistor and the transistor is an "ordinary transistor" or BJT (bi-polar Junction Transistor). For more information on transistor biasing see: Talking Electronics website.
What are operating point int transistor biasing?
A: An operating in biasing is determined by the transistor capabilities as a linear amplifier. Basically it is a bias to insure linear operation with the loading of the output
What the threshold voltage depends on?
It basically depends on the biasing of a transistor. In case of a MOSFET, it depends on the substrate biasing.
How do you define transistor biasing?
Selection and setting of a transistor's operating pointto meet circuit functional requirements.
Is paper capacitor use in transistor amplifier?
It can be, but may not be required. Capacitors are used for biasing purposes, to remove DC from inputs, and for filtering in amplifier circuits (just to name a few).
