Constant current generators (CCGs), as the name suggests, are circuits designed to produce a steady load current regardless of significant fluctuations in load resistance or voltage levels. Basic Constant Current Generator Circuit Illustrated in Figure 1 is a basic example of such a circuit. In this configuration, Q1 operates in the common emitter mode. A […]

SCR/Thyristor Circuit Configurations
Now in this article we will try to understand step by step how we can use this thyristor in practical work. That can be for controlling heavy loads like electric lamps, heaters, or motors and so on. So this part is more about real application and not only about theory. How We Trigger The Thyristor […]
How to Make Logic Gates using Transistors
In this post I have explained how to build NOT, AND, NAND, OR, and NOR logic gates using discrete transistors. The main advantage of using transistor logic gates is that they can work even with voltages as low as 1.5 V. In some electronic applications the available voltage may be inadequate to power TTL or […]
How to Calculate Zener Diode Resistor
In this article I have explained how to calculate and the find the value of the zener diode resistor using simple formulas. What is a Zener Diode Zener diodes are semiconductor devices which are used for regulating an input DC voltage to any desired output voltage. The regulated output voltage value directly depends on the […]
Understanding Bipolar Junction Transistors (BJTs)
If we look at the diodes, their internal construction look very simple. They are made by joining two pieces of semiconductor material, and this is called a pn-junction. But when we talk about bipolar junction transistor or bjt, then things get little more complicated. It needs adding one more layer of semiconductor material, and that […]
How Load Conducts in Half-Bridge Driver Circuits like IR2184 or IR2110
Many folks, especially beginners, they get fully confused when they try to use a half-bridge driver circuits using ICs like IR2184 or IR2110. They look at the datasheet diagram and start thinking, “Bro, how the load will conduct? The MOSFETs are switching one by one so how the current will pass through the load? Looks […]
