In this article I have explained how to make a simple laser communicator circuit for sending and receiving data through laser beam. Laser has been a boon since its invention. Laser is used in wide variety of applications, from Blu-ray driver to high powered cutting torch. There are also many classifications of laser technologies. Here […]

DC Biasing in Transistors – BJTs
In simple terms, biasing in BJTs may be defined as a process in which a BJT is activated or switched ON by applying a smaller magnitude of DC is across its base/emitter terminals so that its is able to conduct a relatively larger magnitude of DC across its collector emitter terminals. The working of a […]
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 […]
Ohm’s Law/Kirchhoff’s Law using Linear First-Order Differential Equations
In this article I have explained Ohm’s Law and Kirchhoff’s Law through standard engineering formulas and explanations, and by applying linear first-order differential equation to solve example problem sets. What’s an Electric Circuit A simplest electric circuit is generally in the form of a series circuit having an energy source or electromotive force input, like […]
Load-Line Analysis in BJT Circuits
So far we have been studying BJT analysis dependent on the level of β over their corresponding operating points (Q-point). In this discussion we will check out how a given circuit conditions can help in determining the possible range of operating points or Q-points and in establishing the actual Q-point. What is Load Line Analysis […]
Emitter-Stabilized BJT Bias Circuit
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 […]
