TP-Link’s Tapo P110M smart plug: Matter and energy monitoring matter
A seemingly newer device reverts to a legacy processor architecture, in comparison to one certified earlier that same year. Does it matter? And was it due to Matter?

Measurement bandwidth
Designers and test engineers should carefully consider an application’s bandwidth requirements before selecting an instrument.
Engineers want accurate measurements over as broad a frequency range as possible. The commonly heard phrase is that…
Practical design for a multi-output flyback converter with improved cross-regulation
A stacked-output topology, combined with a weighted feedback network, improves cross-regulation in multi-output flyback converters. This approach allows the main regulated output and the stacked auxiliary output to contribute to the feedback…
The multi-gig Ethernet migration: Motivations and implementations
Supplier “push” and consumer “pull”. When their efforts coordinate, moving the market in the same direction, the result can be meaningfully impactful.
Toward the beginning of last month’s introductory small form-factor pluggable (SFP)…
GaN FET meets megawatt-scale demands
Renesas is sampling what it says is the industry’s first 650-V GaN FET with dual-side cooling for high-density power conversion in 800-V HVDC AI data centers. The TP65H020G4PLSGBD also has a 20-mΩ on-resistance that Renesas says is among…
FPGA IP accelerates deterministic networking
Orthogone’s Ultra-Low-Latency (ULL) FPGA IP Portfolio comprises production-ready networking and data-movement IP cores for AMD UltraScale+ and Versal adaptive platforms. The IP cores are designed for applications requiring determinism, low…
Microphone array advances acoustic detection
The NOVA32 evaluation kit from sensiBel features a spiral array of 32 optical MEMS microphones for edge AI acoustic-detection applications. An XMOS XCORE.AI processor synchronizes the microphone data into a single 24-bit, 32-channel USB audio…
Quad beamformer simplifies X-band radar design
Qorvo’s QPX0252 four-channel beamformer IC operates from 7.9 GHz to 12 GHz for use in X-band phased-array radar systems. It supports four radiating antenna elements, with dual-beam receive and single-beam transmit operation. The device’s…
Global-shutter sensor raises pixel density
At 2.2 µm, Omnivision’s OG05D 5-Mpixel image sensor offers one of the smallest global-shutter pixel sizes with HDR in its class. The color CMOS sensor is designed for industrial machine vision applications, including compact AI cameras and…
An unbuttoned circuit for setting digital pots
This Design Idea enables you to program digital potentiometers with inexpensive rotary incremental encoders.
Recent Design Ideas for circuits that manually control digital potentiometers have mostly “revolved” around UP/DOWN pushbutton switches.…
Training and inference: Two faces of AI compute
There are two major workloads that make up AI compute: training and inference. Training looks back. It digests a frozen body of past text, images and code, and distills it into weights. Inference looks forward. It takes those weights and, one…
Reducing I/O requirements for optical detection
Although this project may be a bit esoteric, the concepts shown to reduce I/O requirements can also be applied to other systems.
I designed a device that has, as part of its function, multiple pipes which are referred to as silos. These silos…
