Analog Wire

  • During the holidays, it is often a time of reflection and giving thanks for all of the wonders in our lives. One which is very dear to me as an “Electrical Engineer” is electricity, which gives my profession a reason for staying up all night...
  • Configuration of inductance-to-digital converter (LDC) sensors can seem quite challenging, but by using the graph introduced in this blog post, the process can be greatly simplified. For LDCs, a sensor is a simple inductor, spring, or PCB coil in parallel...
  • Baluns are often used to convert a single-ended signal to differential, without adding noise and while maintaining good distortion. A common example of that is in the driver circuit for a high-speed, differential-input analog-to-digital converter (ADC...
  • To pick the right isolator for a system, a design engineer must understand what component-level isolation parameters define an isolator’s high-voltage performance, how these parameters are tested and certified, and why these parameters are relevant...
  • In the world of isolation technology, designing a reinforced digital isolation integrated circuit (IC) that meets the performance specifications and standards of the harsh industrial environment is challenging. Testing and delivering such an isolator...
  • If you are a power supply designer, then isolation is often a concern when dealing with high-voltage switching converters. It is very common to use some form of isolation between the high-voltage primary voltage and secondary low voltages. The feed-back...
  • If you have ever felt the “click” of a button on your computer mouse or the “bump” of the home key on a smartphone, you know the feeling of tactile feedback, also known as haptic feedback. But why do some user interfaces not “click”...
  • In my previous blog post , I outlined the fact that differential signaling can still be negatively impacted by common mode noise. In this post, I will outline some methods that you can use to reduce the impact of common mode noise on differential signal...
  • In my last post , I explained the importance of JESD204B subclasses and reviewed the details of subclass 0 and 1. Today, I’ll explore subclass 2. Subclass 2 Subclass 2 analog-to-digital converters (ADCs) and digital-to-analog converters (DACs...
  • Most of the JESD204B standard addresses the data interface between logic devices and converters, so what are the clocking requirements? For JESD204B subclass 1, the clocking requirement is quite simple: use the SYSREF rising edge to mark the device clock...
