In my first blog about calibration [ 1 ], I discussed calibrating inputs using techniques that tolerated offsets by simply including them in the measurements. In this blog I will look at nullifying the offsets. The initial approach is to build in ...
In the comments to my series of blogs on temperature measurement on the late, lamented Microcontroller Central, there was some feeling that a blog on calibration of analog IO might be a good idea. Let me start by taking you back to some high school ...
We’ve come to expect the U.S.-based global positioning system (GPS) to be available and ubiquitous for the countless military, commercial, and consumer applications dependent on it. Its diverse uses represent a huge leap from its original ...
This design based on an SR latch and two RC networks is, unlike many alternative solutions, neither complex nor expensive. Single and differential capacitance sensors are widely used to measure linear and angle displacement, pressure, proximity, ...
Abstract This article discusses the need for precise gate voltage control and accurate gate measurements when using gallium nitride field-effect transistors (GaN FETs). High-side gate measurements taken with advanced isolated probes are compared to ...
I have always been intrigued by the many ways scientists and engineers have devised to sense basic physical parameters such as temperature, pressure, voltage, current, and electric fields, to cite just a few. In some cases, the challenge is the ...
Abstract This article describes a circuit that facilitates the measurement of currents from amps to hundreds of amps with a high degree of precision. Introduction There are many applications that require the measurement of current. Many digital ...
With the trend toward miniaturization, temperature effects in power electronics are more pronounced than ever. If you’re dealing with temperature fluctuations in your circuit, you may need a stabilization system to keep the temperature ...
I’ve been working with dc power supplies and batteries for over 30 years now and every day I employ Ohm’s Law, V = I R, to solve some problem or make some calculation related to dc power. If current is flowing, then there’s a ...
High-resolution mixed-signal devices present an interesting challenge as you try to find the right voltage-reference design. Although no universal approach exists for these voltage-reference designs, the circuit in Figure 1 presents an interesting ...
