Which of the following device is used in compensation technique?
Solution: A diode is used as the compensation element used variation in VBE and ICO. The diode used is of the same material and type as that of transistor. Hence, the voltage across the diode has same temperature coefficient as VBE of the transistor.
What is diode compensation technique?
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.
Which of the following components are used for bias compensation in transistor circuits?
Which of the following components are used for bias compensation in transistor circuit? Rectifier diodes.
What are the different methods for biasing the transistor?

- Base Bias with Emitter Feedback. …
- Base Bias with Collector Feedback. …
- Base Bias with Collector And Emitter Feedbacks. …
- Emitter Bias with Two Supplies. …

Why compensation techniques are used?
Explanation: Compensation techniques refer to the use of temperature sensitive devices such as thermistors, diodes, transistors, sensistors etc to compensate variation in currents. Sometimes for excellent bias and thermal stabilization, both stabilization and compensation techniques are used.
Why is self bias circuit not used in IC amplifier?
Explanation: Self biased circuits are not preferred in IC amplifiers because they need large resistances R1 and R2, since then S will be smaller and stability will be more.
Which biasing circuit is not suitable for biasing Mosfet?
Explanation: To bias an e-MOSFET, we cannot use a self bias circuit because the gate to source voltage for such a circuit is zero. Thus, no channel is formed and without the channel, the MOSFET doesn’t work properly.
What are the four types of compensation?
The Four Major Types of Direct Compensation: Hourly, Salary, Commission, Bonuses. When asking about compensation, most people want to know about direct compensation, particularly base pay and variable pay.
What is the difference between bias stabilization and bias compensation?
Explanation: Bias compensation is a technique that we use to stabilize temperature of the operating 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.
Which of the following compensation techniques bandwidth increases?
(d) Phase lead compensation decreases the system bandwidth, whereas the phase lag compensation increases the system bandwidth.
What is compensation circuit?
Abstract: Compensation circuits in the inductive power transfer system (IPTS) vary depending on applications. A basic and widely used compensation scheme with single magnetic coupling and two capacitors is explained in this chapter.
What is are the purpose s of adopting stabilization and compensation techniques?
What is /are the purpose/s of adopting stabilization and compensation techniques? Explanation: In some of the negative feedback circuits, the amplification level of AC signals gets ablated rapidly. … They play a major role in given that maximum bias in addition to the thermal stabilization to the circuits.
