How BJTs Work

Let’s go into more detail on how the BJT (bipolar junction transistor) works.

The last article on transistors (An Introduction to Transistors) started with a little history on the devices and what was in use before them. Then, it glossed over the two main types you’ll work with: BJTs and MOSFETs. Finally, the two modes of transistor operation were briefly discussed.

This time, we’re going to take a deeper dive into BJTs specifically. This article will go into a bit more detail on how the BJT or bipolar junction transistor works and some basics on using them in your creations.

Intro to Analog to Digital Converters

2 Comments

Like digital to analog converters or DACs, the analog to digital converter or ADC is everywhere.

A while back, I published an article on DACs titled Digital to Analog Converters – An Introductory Tutorial. I strongly advise you check it out before reading this article if you haven’t already.

There are a few reasons for this. First, some analog to digital converters use DACs as part of their makeup. Second, a lot of the specs that apply to DACs also apply to analog to digital converters. Finally, ADCs are more complicated, but a good understanding of DACs can help you better understand how ADCs work.

Like the DAC post, this one is introductory, so we won’t cover every analog to digital converter that exists; rather I’ll discuss the most common ones in use today. [Read more…] about Intro to Analog to Digital Converters

Welcome to C Programming Tutorial 7, Arrays in C Part 2!

C Tutorial 6 was an introduction to arrays in C.

This time, we’re going to go into a little bit more detail about arrays after a quick review.

An Introduction to Transistors

7 Comments

When someone poses the question what is a transistor or how does a transistor work they can literally find tons of material that answers those questions and gives more detail than perhaps one would care for.

Indeed, many books exist on the subject of transistors, semiconductor physics, transistor characteristics, and their operation. They range from the beginner level to the engineering level and even on to cutting edge research and new breakthroughs in the design of transistors and semiconductors.

Because of this, the answers you will find to the questions above (and similar ones) range from the simplistic to the extremely complicated.
