Kinds Of Operational Amplifiers

There are various types of electrical and electronic components which are typically used to design electronics projects and circuits. These components include, operational amplifiers, integrated circuits, microcontrollers, microprocessors, digital logic gates, analog to digital or digital to analog converters, and so on. Let us consider operational amplifier, which can be defined as an electronic device which takes differential input and thereby generates a single ended output and is termed as a DC coupled high-gain electronic voltage amplifier. In this article, let us discuss about the op amp circuits and basics. Op Amp Circuit The operational amplifier can be used to […]

Capacitors

A capacitor is a two-terminal, electrical component. Along with resistors and inductors, they are one of the most fundamental passive components we use. You would have to look very hard to find a circuit which didn’t have a capacitor in it. What makes capacitors special is their ability to store energy; they’re like a fully charged electric battery. Caps, as we usually refer to them, have all sorts of critical applications in circuits. Common applications include local energy storage, voltage spike suppression, and complex signal filtering. Circuit Symbols There are two common ways to draw a capacitor in a schematic. […]

Diodes

Introduction Once you graduate from the simple, passive components that are resistors, capacitors, and inductors, it’s time to step on up to the wonderful world of semiconductors. One of the most widely used semiconductor components is the diode. In this tutorial we’ll cover: What is a diode!? Theory of diode operation Important diode properties Different types of diodes What diodes look like Typical diode applications Suggested Reading Some of the concepts in this tutorial build on previous electronics knowledge. Before jumping into this tutorial consider reading (at least skimming) these first: What is Electricity Voltage, Current, Resistance, and Ohm’s Law […]

Resistors

Resistors, ( R ) are the most fundamental and commonly used of all the electronic components, to the point where they are almost taken for granted. There are many different Types of Resistor available for the electronics constructor to choose from, from very small surface mount chip resistors up to large wirewound power resistors. The principal job of a resistor within an electrical or electronic circuit is to “resist” (hence the nameResistor), regulate or to set the flow of electrons (current) through them by using the type of conductive material from which they are composed. Resistors can also be connected […]

Transistors

Transistors can be regarded as a type of switch, as can many electronic components. They are used in a variety of circuits and you will find that it is rare that a circuit built in a school Technology Department does not contain at least one transistor. They are central to electronics and there are two main types; NPN and PNP. Most circuits tend to use NPN. There are hundreds of transistors which work at different voltages but all of them fall into these two categories. Transistors are manufactured in different shapes but they have three leads (legs). The BASE – […]

Difference Between an NPN and a PNP Transistor

Difference Between an NPN and a PNP Transistor Before we talk about the differences between NPN and PNP transistors, we will first discuss what they are and their similarities. Both NPN and PNP are bipolar junction transistors (BJTs). BJTs are current-controlled transistors that allow for current amplification. A current input into the base of the transistor allows for a much larger current across the emitter and collector leads. NPN and PNPs are exactly the same in their function, they provide amplification and/or switching capability. So technically, they achieve and do the same exact thing. How they differ is how power […]
