    Is charge injection causing output voltage errors in your industrial control system?

    Designers working on fast-switching data-acquisition systems often complain about random spikes, fluctuations, excessive noise or other kinds of unexpected voltage on their analog input channels. The common reason for these problems is impedance mismatching. When driving multiplexed systems with a high source impedance compared to the input impedance...

    Finding the right pixel clock frequency and throughput for an LVDS display resolution

    Low voltage differential signaling (LVDS, also known as OpenLDI ) thin-film transistor (TFT) liquid crystal (LCD) displays typically have a specified resolution and minimum required clock frequency to meet desired resolution. Normally, you will find this information listed in the display data sheet and won’t need to perform any calculations. ...

    Intro to linear Hall effect sensors: Achieve contactless accurate position sensing

    As consumers, we tend to overlook the technology that surrounds us today. Take, for instance, the trigger on your game controller. You’re playing as an archer, and the trigger mimics the action of using a bow and arrow. To draw the bow you depr...

    Getting smart about stepper tuning

    When I first heard about stepper tuning, I was really confused. How can a motor be out of tune? I started reminiscing about warming up for band concerts in high school, and wondered how system designers could do something similar for their motors. After watching a video from my colleague Matt Hein I learned these three things about stepper tuning...

    Strengthening overvoltage protection for USB connectors in mobile applications

    USB Type-C™ is changing how we connect and use our devices. With the availability of higher voltages at the USB Type-C connector through USB Power Delivery (USB PD), you need to include greater levels of protection in order to safeguard critical system components. One element to consider is overvoltage protection (OVP), which protects against...

    What is an EFT? Part 2

    In my last post , I discussed what an electrical fast transient (EFT) is at a high-level. For part two, let’s explore why EFTs matter and why they should be considered during your design process. Ultimately, EFTs matter for two key reasons: First, acceptable amounts of interference will vary greatly from application to application and could...

    Create an eye-opening experience with a 10G USB3 redriver

    Signal integrity, the measure of electrical signal quality, can be visualized by displaying a signal waveform on an oscilloscope. This visualization is commonly known as an eye diagram, and is generated by overlaying the waveform’s positive and negative bits. When superimposed, these bits produce an image that resembles an open eye, hence the...
