Precision Current Source : Part Three

In this post, we will finally look at the working Precision Current Source. We will assemble the device and calibrate it using a 34465A bench multimeter. Finally, I got this project almost to the finish line. I will tell you what is remaining. But for now, I am happy with how this project turned out. Precision Current Source Specification The…

Precision Current Source : Part Two

While working with precision sources, we have to consider its accuracy over its full usable temperature range. We will discuss potential ways of minimizing temperature drift due to trimmer potentiometer (POT). The accuracy of the current output depends on the values of the resistor ratio formed by the resistors. But using a trimmer potentiometer, we can overcome the total errors…

A Brief Guide to Temperature Sensing

Today, we will look at different options we have for temperature sensing. To try and understand the strength and weaknesses of each method. By the end, we will figure out which technology is right for a given use-case in this brief guide to temperature sensing. A Brief Guide to Temperature Sensing The following list doesn't include temperature sensing devices/methods which…
