NPN Transistor Principles and Practical Uses

Basic NPN Transistor Principles Universities are covering this topic very well but despite I still attempt to discuss NPN transistor

Transistor operation mode is can easily be determined by using mathematical equations. Don’t worry; these are not difficult equations. There

In this article I will discuss the feature of the NPN transistor biasing tool and checker in excel that I

This article will uncover the fixed bias configuration with a divider resistor complete analysis. Actually this is another variation of

This article will uncover the complete analysis of a fixed bias circuit. Figure 73 below shows a simple common emitter configuration.

There are few things to consider on how to select a transistor. Specific application requires a perfect match device so

PNP transistor is very useful in high side driving. A successful high side driving circuit starts with the proper understanding

There are several ways how to know if a transistor is saturated or not. It is very important that if

How to drive a transistor into hard saturation? In using a transistor to operate as a switch you must drive

BJT operation modes are at cut-off, saturation and active or linear. At cut-off, simply the BJT is not operating, say the base-emitter
