A Precision Arduino Thermocouple Measuring System

A Precision Arduino Thermocouple Measuring System This post provides Arduino enthusiasts with the technical framework to develop a high quality Arduino Thermocouple measuring system. It also provides the basics to encourage young Arduino users to get a project up and running. We keep the topics as brief as possible to encourage our young friends.  The more […]

ADC resolution, ADC offset error and Gain error getting 12 bit from 10 bit ADC

ADC resolution, ADC offset error and Gain error Maximizing the ADC performance Part 1 The life of a design engineer is filled with failure during testing and then the last minute rework and meet deadlines. Any engineer dealing with data converters (ADCs and DACs) will at some point find out that the part does not meet […]

Finite Element Method Application in Electrical Engineering

Abstract  This paper deals with Finite Element Method (FEM) of analyzing different types of physical systems. Mathematical systems of equations that describe physical systems are often too complex for analytical solving. FEM is a numerical method used for solving these systems. It breaks up the system into the group of elementary elements, called “finite elements”. […]

DC to DC Converter Performance Testing

In this application note, we introduce the important performance characteristics of DC to DC converters and testing methods. The testing circuits and operation are also discussed. Note that the importance of each performance characteristic is dependent on the end application. As such, more detailed testing and methods may be warranted. This is left to the […]

High Performance Heat-spreader for Heatsink

Using heat sink specification provided by manufacturers requires understanding of thermal design. Most design engineer not trained in heat transfer can erroneously rely on the published specifications for heat-sink selection. The heat flux present at the semiconductor transfer surface can reduce the published performance specification due to thermal resistance of the material at the mating […]

Introduction to stepper motor specifications and voltage mode drive

Nesh Basnet,  Shiraz Macuff,  Subash Shrestha,  Lhakpa Dhondup,  Lobsang Lekshey, Anil Rajpatei,  Francisco Santos,  Adrian Serrano Abstract This application note gives a brief introduction to stepper motor specification and voltage mode drive method. We look at drive requirements once the motor has been chosen and give several application examples. A method for increasing the stepping […]
