Comparing MOSFETs with BJTransistors – Pros and Cons

Last Updated on May 20, 2026 by Swagatam 4 Comments

mosfetandtransistorpinouts

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

Last Updated on May 20, 2026 by Swagatam 93 Comments

pinout

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 […]

Introduction to Schmitt Trigger

Last Updated on May 20, 2026 by Swagatam Leave a Comment

Almost any digital circuit used in modern high-speed data communications needs some form of Schmitt trigger action on its inputs. Why Schmitt Trigger is Used The main purpose of a Schmitt trigger here is to eliminate noise and interference on data lines and provide a nice clean digital output with fast edge transitions. The rise […]

Basics of Strain Gauge Measurements

Last Updated on May 20, 2026 by Swagatam 2 Comments

wheatstone bridge circuit

The strain gauge is one of the most useful tools for precisely measuring expansion or contraction of a material as forces are applied. Strain gauges are also useful for measuring applied forces indirectly if they are aligned approximately linearly with the deformation of the material. What are Strain Gauges Strain gauges are sensors whose electrical […]

How to use Eagle CAD

Last Updated on May 20, 2026 by Swagatam 1 Comment

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 […]

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 […]
