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…
Past, present, and future of hard disk drives (HDDs)
Where do HDDs stand after the advent of SDDs? Are they a thing of the past now, or do they still have a life? While HDDs store digital data, what’s their relation to analog technology? Here is a fascinating look at HDD’s past, present, and…
Improve PWM controller-induced ripple in voltage regulators
Simple linear and switching voltage regulators with feedback networks of the type shown in Figure 1 are legion. Their output voltages are the reference voltage at the feedback (FB) pin multiplied by 1 + Rf / Rg. Recommended values of Cf from…
A transistor thermostat for DAC voltage references
Frequent contributor Christopher Paul recently provided us with a painstakingly conservatively error-budget-analyzed Design Idea (DI) for a state-of-the-art pursuit of a 16-bit-perfection PWM DAC.
The DI presented below, while shamelessly…
