Introduction to Electronic Devices and Circuits Notes

In the most basic sense, electronic engineering deals with the flow of electrons in semiconductors, gas, and vacuum tubes. The various applications of electronics include medical and home appliances, computer and mobile communications, robotics, etc.

The movement of electrons through a conveyor gives us electric flow. This electric flow can be delivered with the assistance of batteries and generators. The gadget which controls the progression of electrons is called an electronic device. These gadgets are the fundamental structure squares of electronic circuits. Gadgets have different branches incorporating analog electronics, digital electronics, microelectronics, nanoelectronics, optoelectronics, coordinated circuit, and semiconductor gadget.

All circuit branch engineers require the basic knowledge of this subject to function properly in this area. Electronic Devices and Circuits aim to familiarize students and aspirants with amplifier circuits, design and analysis of junction diode, the principle of operation, and BJT as well as FET transistors. In addition to this, the subject intends for the understanding of the diode as a rectifier to propagate the basic principle of the filter of circuits along with its various types.

Frequently Asked Questions on Electronic Devices and Circuits

Question 1.
What is meant by a Zener Diode?

At the point when the reverse voltage arrives at breakdown voltage in ordinary PN junction diode, the current through the intersection and the force dispersed at the intersection will be high. Such activity is ruinous and the diode gets harmed. While diodes can be planned with sufficient power dissipation abilities to work in a separate district. One such diode is known as the Zener diode.

Question 2.
What are the different Transistor Configurations?

The different Transistor configurations are as follows:

  • CB (Common bank) configuration.
  • CE (Common emitter) configuration.
  • CC (Common collector) configuration.

Question 3.
Can one utilize these notes for revision during exams?

The EDC notes have been formulated with a chief agenda of securing good scores in the B. Tech 1st semester exams. They are extremely comprehensive and provide detailed explanations with the accurate organisation of the different topics. Students can completely rely on these notes for revision during exams.

Question 4.
Explain the limitations of h-parameters.

The 2 chief limitations of h-parameters are as follows:

  • It provides the right answers only for A.C signals. This is due to the reason that a transistor behaves as a linear device only for small signals.
  • For a particular transistor, finding the exact values for h-parameters can prove to be reasonably difficult. This is because parameters are subject to the unit to unit variation, due to change in temperature and change in operating point.
