Understanding Signal Reflections for High-Speed Design

Understanding Signal Reflections for High-Speed Design Introduction Signal reflections and the engineering related to impedance matching are one of the basic topics related to design of high-speed digital systems. In the case of digital system with a high bit rate, in which information about the state of bits "0" and "1" is sent in the form of a square wave signal, it is assumed that the rise (or fall) time of the rising and falling edges are negligible in relation to the binary signal frequency.

Signal Integrity Principles based on Altium Designer 24 Introduction to High-Speed and Signal Integrity Digital systems are one of the fundamental areas of modern electronics. The advancement in highly efficient processors or other digital systems, like FPGAs or wide-bandwidth data acquisition systems that use fast ADCs converters together with DSPs or FPGAs, requires a different approach to electronic design, especially PCB that includes interconnects between various integrated circuits or modules Read Article

Mastering EMI Control in PCB Design: Component Placement for EMC

Mastering EMI Control in PCB Design: Component Placement for EMC In this second article of the Mastering EMI Control in PCB Design series, we will dive deeper into one of the key concepts for maintaining low levels of electromagnetic interference (EMI). Board segregation, also known as board partitioning, is a method used to organize the different circuit parts of a Printed Circuit Board (PCB) to keep them separate. This improves the overall performance of the board, particularly in terms of EMI. This Read Article

Carry Propagation Delay in High Speed Data Processing

What is Carry Propagation Delay in High Speed Data Processing? I sometimes get into text message conversations with friends that go completely haywire. It’s too easy to ask five questions back and forth in a single text, and trying to respond to everything causes our message chain to go completely out of sync. It isn’t until three text messages later that I actually respond to everything my friend asked, and by then we’ve moved on to a completely new topic. Signal delay between logic circuits in a PCB or an Read Article

PCB Design Tips for SRAM Users: How to Prevent Data Loss

What is SRAM? PCB Design Tips and How to Prevent Data Loss SRAM loses its data when power is removed. One of the best inventions in editing software is the autosave feature, which prevents Murphy’s Law from striking at the worst time. Decades ago, I nearly cried when several pages of an important university assignment were literally wiped out, as the non-existence of the autosave feature was made worse by my reluctance to hit the ‘Save’ button. In electronics, you risk losing the entire data stored in a Read Article
