More Accurate I/O Models

I/O models have become increasingly important as we’ve moved from dumb 5-V-swing full-rail CMOS I/Os (remember those?) to the tight, sensitive kinds of I/Os needed for serial connections and DDR memory. Along with that we’ve gone from no need for models to the need for very accurate models to ensure that signals will get where they’re going without being swamped by noise.

IBIS models have served that purpose, but they also were pretty rough and ready in their earlier incarnations, requiring manual work to create them.

Sigrity is trying to address this by releasing TB2, a tool that takes a transistor-level design and automatically creates a power-aware IBIS 5.0 model. By starting from the transistor level, the intent is that the model can be much more accurate than what has traditionally been possible.

Configure the backup voltage in a reversible buck/boost regulator

Sponsored by Maxim Integrated

This application note looks at a reference circuit design using Maxim’s MAX38888, which provides a supercapacitor-based power backup in the absence of the system rail by discharging its stored charge. The backup voltage provided by the regulator from the super cap is 12.5% less than the system rail when the system rail is removed. This note explains how to maintain the backup voltage within 5% of the minimum SYS charge voltage.

Cutting the AI Power Cord: Technology to Enable True Edge Inference

Sponsored by Mouser Electronics and Maxim Integrated

Artificial intelligence and machine learning are exciting buzzwords in the world of electronic engineering today. But in order for artificial intelligence or machine learning to get into mainstream edge devices, we need to enable true edge inference. In this episode of Chalk Talk, Amelia Dalton chats with Kris Ardis from Maxim Integrated about the MAX78000 family of microcontrollers and how this new microcontroller family can help solve our AI inference challenges with low power, low latency, and a built-in neural network accelerator.
