What is the purpose of dc biasing of transistor?
to establish Q- point or operating point...
Operating point in the transistor means?
The operating point of a transistor is simply the point, or circuit condition, where it is biased. With no signal present, the operating point sets the collector-emitter current, and the resulting voltages. Ideally, the operating point is chosen to be the midpoint of the linear region of operation, so as to minimize distortion and to maximize range. Since transistors have varying gains (hFe), and since the gain is temperature dependent, the operating point is usually chosen to be a range that also maximizes stability and minimizes the variability of the individual transistor.
What is an operating point of dc load line?
operating point of dc load line refers to point where there is no signal either no amplification use to take place as base current is zero(in case of common emitter configuration) and it is represented by Q.......
Define the operating point of a transistor how it is stabilized and why it should be stabilized?
The operating point of a device, also known as bias point, quiescent point, or Q-point, is the point on the output characteristics that shows the DC collector-emitter voltage (Vce) and the collector current (Ic) with no input signal applied. The term is normally used in connection with devices such as transistors.
Why you are giving dc supply for biasing the amplifier why not ac?
The purpose of biasing an amplifier is to shift its operating point, so that when you apply a signal in you will get a expected signal out. The operating point is generally in the middle of the linear region. You would not use AC for the bias, as that would cause the operating point to constantly shift, and you would then not be able to differentiate between the signal and the bias.
What is operating point instability and need of stabilization?
A: And system or amplifier may have instability as some point due to external or internal function therefore intervention is needed to stabilize the system at that particular point of operation.
Why operating point of transistor is called as q point?
Q-point means motionless point. At operating point the transistor emitter current and collector current doesn't change. That is why operating called as a quiesent point (q-point)
What is the operating point in transistor biasing?
The operating point of a transistor is the point on its conduction curve that the engineer has selected for its operation, based on the intended function of the circuit the transistor is used in. This will vary with this function:a class A amplifier will have its operating point in the center of the linear range of the conduction curve.a class B amplifier will have its operating point at the cut off point of the conduction curve.logic gates will usually have the operating point near the cut off point off the conduction curve.etc.
Is an operating system and power point Computer hard wares?
No. Operating systems and Power Point are examples of computer software.
When was Wage Stabilization Board created?
Wage Stabilization Board was created in 1945.
When was Office of Economic Stabilization created?
Office of Economic Stabilization was created in 1942.
How operating point of transistor shifting?
Usually, the operating point of a transistor shift because of temperature induced gain or bias changes.
If a firms fixed financial costs decrease the firms operating breakeven point will do what?
decrease <--------WRONG!!!!! The operating breakeven point will remain unchanged.
