Partners demo PCIe 6.0 64-GT/s interoperability
Alphawave Semi and Keysight joined forces to accelerate PCIe 6.0 compliance testing and bolster interconnectivity across AI compute infrastructure. The companies demonstrated interoperability between Alphawave’s PCIe 6.0 PHY and controller…
Image sensors facilitate machine vision tasks
Joining Samsung’s ISOCELL Vizion sensor lineup are the Vizion 63D time-of-flight (ToF) sensor and the Vizion 931 global shutter sensor. Tailored for robotics and extended reality (XR) applications, the sensors leverage the company’s ISOCELL…
Hall latches meet AEC-Q100 requirements
Automotive-compliant Hall-effect latches in Diodes’ AH371xQ series have an operating voltage range of 3 V to 27 V, with 40-V load dump protection. Resistant to physical stress, the parts are qualified to the AEC-Q100 Grade 0 standard and operate…
Resettable fuses save space in 1206 packages
Bourns has added 20 new devices to it MF-NSMF series of Multifuse polymer positive temperature coefficient (PPTC) resettable fuses in 1206 size packages. By combining higher power ratings in a smaller footprint, these surface-mount devices give…
MCUs optimize BLDC motor applications
Microchip’s AVR EB family of MCUs provides complex waveform control in systems that employ brushless DC (BLDC) motors. Aimed at a wide range of cost-sensitive applications, the microcontrollers can adjust speed, timing, and waveform shape,…
A simple, accurate, and efficient charge pump voltage inverter for $1 (in singles)
Keeping op-amp outputs “live” at and below zero volts, generating symmetrical output signals, and processing bipolar analog inputs, are all examples of design situations where a few milliamps of negative voltage rail can be a necessity.…
Distortion Factor as a function of total harmonic distortion
Coming to grips with the semantics and vocabulary that apply to “distortion” takes a little discipline, but it isn’t all that intimidating. All you need is a little patience to go over the relevant algebra and not scribble.
Two phrases…
Figuring out a dimmable filament LED light bulb
As also noted previously, I’ve done a lot of LED light bulb teardowns over the years, not even counting LED illumination sources that aren’t bulb-shaped, like touch-activated and motion-sensing panels:
Conventional
Zigbee-controlled
Wi-Fi-augmented
Bluetooth-enhanced
Multicolor
Three-way,…
Analog of a thyristor with a controlled switching threshold
Thyristors are a semiconductor device with an S-shaped current-voltage characteristic. They are a kind of managed keys with a state memory that are turned on when a control signal is applied to the input of the thyristor. When working on direct…
Proper function linearizes a hot transistor anemometer with less than 0.2 % error
A recent Design Idea presents a circuit to measure an airflow rate up to 2000 fpm using two transistors in a Darlington configuration. One transistor works as a self-heated thermal sensor and the other one compensates for ambient temperature…
Application of machine learning in power management systems
Data processing these days is exhibiting a split personality. ‘Cloud’ computing grabs the headlines for sheer scale and computing power, while ‘edge’ computing puts the processing at the ‘coal face’ where electronics interfaces with…
How to control a qubit? With a quantum error correction stack
There are many challenges to build a useful quantum computer. The core issue is that the quantum bits—qubits—that run the quantum calculations are incredibly unreliable, breaking down when they encounter the slightest environmental noise,…
