What is Sensistor compensation?
Sensistor Compensation A Sensistor is a heavily doped semiconductor that has positive temperature coefficient. The resistance of a Sensistor increases with the increase in temperature and decreases with the decrease in temperature.
What is diode compensation?
Diode compensation is a technique that is used to reduce the Q-point variations by selecting a diode that has temperature characteristics similar to the transistor.
What is the basic difference between bias compensation and stabilization?
Bias Compensation and bias stabilization There is another point called diode in compensation which is used to eliminate Q-point. Bias stabilization makes that operating point independent and stable everything on its own. It makes the operating point unaltered by maintaining the changes in it.
What is bias stabilization?
Stabilization. The process of making the operating point independent of temperature changes or variations in transistor parameters is known as Stabilization. Once the stabilization is achieved, the values of IC and VCE become independent of temperature variations or replacement of transistor.
What is the difference between thermistor and Sensistor?
A sensistor is a variable resistance device whose resistance changes with the change in temperature though it is simmilar to a thermistor it has positive temperature coefficient( resistance increases as temp increases) unlike the thermistor which has negative temperature coefficient .
What is thermistor and Sensistor?
Sensistor: Positive temperature coefficient. In semiconductors as temperature increases conductivity increases i.e., it can exhibit positive temperature coefficient of conductivity, this property finds applications in control devices, as a thermal relay etc., Such a semiconductor is called as thermistor.
What is Compensation technique?
The compensation techniques are the methods that are employed in the electrical control systems to enhance the performance of the system. The performance are generally affected by the factors like lag in the compensating devices, slow response of the system of the components like sensors used in the control system.
Why Compensation technique is required?
The main reason for reactive power compensation in a system is: 1) The voltage regulation 2) Increased system stability 3) Better utilization of machines connected to the system 4) Reduction in losses associated with the system 5) To prevent voltage swell as well as voltage sag.
What is meant by Compensation technique?
It refers to the use of temperature sensitive devices such as diodes, transistors, thermistors which provide compensating voltage and current to maintain Q point stable.
What is compensation technique?
What is amplifier bias?
In an amplifier, a bias is a steady current or a steady voltage that stays in the circuit even when the volume control is set to zero. Vibrating guitar strings produce a fluctuating current or voltage (a signal) that gets superimposed on the steady bias. The guitar signals can be distorted by the amount of bias.
What is the working principle of thermistor?
The working principle of a thermistor is that its resistance is dependent on its temperature. We can measure the resistance of a thermistor using an ohmmeter.
