A configuration in which a bipolar junction transistor or a BJT is reinforced with an emitter resistor for enhancing its stability with regards to changing ambient temperatures, is called an emitter stabilized bias circuit for BJT. We have already studied what is DC biasing in transistors, now let’s move ahead and learn how an emitter […]

How to Understand and Use white LEDs – Datasheet
If you are wondering how to correctly use white LEDs in circuits so that they can be illuminated safely without damaging, then this post might help you to evaluate the same. Introduction White LEDs are the future lighting solutions for our cities and homes. They will be easily replacing the traditional CFL and other flurescent […]
How to use Eagle CAD
Eagle CAD is a Professional PCB design package from the German company CadSoft. It offers an array of licenses, some of which allow individuals to use the package virtually free of charge. The learning curve may be a bit steep, but then Computer Aided Drafting is hardly simple, and most CAD packages have steep learning […]
Capacitive Voltage Divider
In this post I have explained how capacitive voltage divider circuits operate in electronic circuits, through formulas and solved examples. By: Dhrubajyoti Biswas What is a Voltage Divider Network Talking about a voltage divider circuit, it is important to note that voltage in divider circuit gets equally distributed among all the existing components associated with […]
What is Transistor Saturation
In the previous post I explained BJT biasing, in this article I have explained what is transistor or BJT saturation and how to determine the value quickly through formulas and practical evaluations. What is Transistor Saturation The term saturation refers to any system where the specification levels have attained the maximum value. A transistor may be said […]
Difference Between Alternating Current(AC) and Direct Current(DC)
In this post we try to investigate the mains differences between alternating current (AC) and direct current (DC). The word AC and DC are pretty common with electronics and we all come across it while developing or dealing electronic circuit designs. Overview Though the terms are very ordinary with the field, many noobs become confused […]
