The field-effect transistor (FET) is an electronic device in which an electric field is used to regulate the flow of current. To implement this a potential difference is applied across the gate and source terminals of the device, which alters the conductivity between the drain and source terminals causing a controlled current to flow across […]

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 […]
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 to Configure Resistors, Capacitors and Transistors in Electronic Circuits
In this post we try to evaluate how to configure or connect electronic components such as resistors, capacitors withing electronic circuits through correct calculation Kindly read my previous post regarding what is voltage and current, in order to grasp the below explained basic electronic facts more effectively. What is a Resistor – It is an […]
How PNP Transistors Work
In this post I have explained regarding how a PNP transistor works or conducts in response to a fixed biasing voltage and a varying supply voltage, across its base and emitter. The question was put forth by Mr. Aaron Keenan. Question Regarding PNP BJT Working Great information and lots of interesting circuits!I have a question […]
High Voltage Transistors BUX 86 and BUX 87 – Specifications
In this article we are going to make an effort to understand the technical specs of the BJTs BUX86 and BUX87 which are high voltage complementary paired transistors. Introduction The Bux 86 and BUX 87 are typically high voltage switching transistors with silicon epibase. They come in TO-126 package and are NPN types. These devices […]
