Next-gen UWB radio to enable radar sensing and data streaming applications
Since the early 2000s, ultra-wideband (UWB) technology has gradually found its way into a variety of commercial applications that require secure and fine-ranging capabilities. Well-known examples are handsfree entry solutions for cars and buildings,…
A digital frequency detector
I designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation.
I needed to detect the presence of the carrier by distinguishing it from other signals of…
Can a smart ring make me an Ultrahuman being?
In last month’s smart ring overview coverage, I mentioned two things that are particularly relevant to today’s post:
I’d be following it up with a series of more in-depth write-ups, one per ring introduced in the overview, the first of…
Universal homing sensor: A hands-on guide for makers, engineers
A homing sensor is a device used in certain machines to detect a fixed reference point, allowing the machine to determine its exact starting position. When powered on, the machine moves until it triggers the sensor, so it can accurately track…
Amazon and Google: Can you AI-upgrade the smart home while being frugal?
The chronological proximity of Amazon and Google’s dueling new technology and product launch events on Tuesday and Wednesday of this week was highly unlikely to have been a coincidence. Which company, therefore, reacted to the other? Judging…
PoE basics and beyond: What every engineer should know
Power over Ethernet (PoE) is not rocket science, but it’s not plug-and-play magic either. This short primer walks through the basics with a few practical nudges for those curious to try it out.
It’s a technology that delivers electrical…
Image sensor provides ultra-high dynamic range
Omnivision’s OV50R40 50-Mpixel CMOS image sensor delivers single-exposure HDR up to 110 dB with second-generation TheiaCel technology. It also reduces power consumption by ~20% compared with the previous-generation OV50K40, enabling longer…
Dual-core MCUs drive motor-control efficiency
RA8T2 MCUs from Renesas integrate dual processors for real-time motor control in advanced factory automation and robotics. They pair a 1-GHz Arm Cortex-M85 core with an optional 250-MHz Cortex-M33 core, combining high-speed operation, large…
Platform speeds AI from prototype to production
Purpose-built for Lantronix Open-Q system-on-modules (SOMs), EdgeFabric.ai is a no-code development platform for designing and deploying edge AI applications. According to Lantronix, it helps customers move AI from prototype to production in…
Co-packaged optics enables AI data center scale-up
AIchip Technologies and Ayar Labs unveiled a co-packaged optics (CPO) solution for multi-rack AI clusters, providing extended reach, low latency, and high radix. The joint development tackles AI infrastructure data-movement bottlenecks by replacing…
DMD powers high-resolution lithography
With over 8.9 million micromirrors, TI’s DLP991UUV digital micromirror device (DMD) enables maskless digital lithography for advanced packaging. Its 4096×2176 micromirror array, 5.4-µm pitch, and 110-Gpixel/s data rate remove the need for…
Thermally enhanced packages—hot or not?
The relentless pursuit of performance in sectors such as AI, cloud computing, and autonomous driving is creating a heat crisis. As the next generation of processors demand more power in smaller spaces, the switched-mode power supply (SMPS) is…
