In this post I have explained a voltage high current doubler circuit which will almost double the voltage that’s been applied at the input (up to 15V max), and also it becomes specifically useful since it allows higher current loads to be used at the output, in the order 10 amps. Since the voltage doubler […]

How to Connect a Relay through an Opto-Coupler
In the following post I have explained how to drive a relay by using an isolated method, or through an optocoupler device. We will learn three methods, first method is by connecting relay directly with the optocoupler output pins, second method is by using external PNP transistors, and third method is by using external NPN […]

The IC 555 is an extremely useful and versatile device which can be applied for configuring many useful circuits in the field of electronics. One very useful feature of this IC is its ability to generate PWM pulses which can be dimensioned or processed as per the needs of the application or the circuit. What’s […]
Comparing MOSFETs with BJTransistors – Pros and Cons
The post comprehensively discusses the the similarities and difference between mosfets and BJTs and also their particular pros and cons. Introduction When we talk of electronics, one name becomes extremely related or rather common with this subject and that is the transistors, more precisely the BJT. Electronics is in fact based on these outstanding and indispensable member, without which […]
How to Replace a Transistor (BJT) with a MOSFET
In this post I have explained the method of correctly replacing a BJT with a MOSFET, without affecting the final outcome of the circuit. Introduction Until MOSFETs arrived in the field of electronics, transistors or BJTs to be precise ruled the power switching circuits and applications. Though even Bipolar Junction Transistors (BJTs) can not be […]
