Power Tips #133: Measuring the total leakage inductance in a TLVR to optimize performance
A trans-inductor voltage regulator (TLVR) modifies the conventional multiphase buck converter, accelerating the converter’s output current slew-rate speed capabilities to approach the fast load slew rate of the high-speed processor or application-specific…
EDA’s big three compare AI notes with TSMC
The premise of artificial intelligence (AI) transforming the semiconductor industry is steadily taking shape, and two critical venues to gauge the actual progress are leading EDA houses and silicon foundries. The three major EDA toolmakers—Cadence,…
Cracking the case of a smartphone and its unfairly crack-accused case
By the time you read this, you likely will have already seen my upcoming coverage of Google’s August product announcement event in a bit more than a week (as I write this), where the Pixel 9 series is forecasted to be introduced. However,…
EMC: How to write a good benchtop test report
Before we delve into a step-by-step guide to good engineering practice, two thoughts to keep in mind. First, there are too many subpar test reports from engineers, who often do excellent work but aren’t given enough time to document it properly.…
SoC simplifies smart home connectivity
Leveraging Qorvo’s ConcurrentControl technology, the QPG6200L SoC supports Matter, Zigbee, and Bluetooth LE networks. As the first product based on this low-power wireless technology, it enables coexistence across different radios and channels…
Arduino Cloud launches on AWS Marketplace
Amazon Web Services (AWS) customers can now access Arduino Cloud directly through the AWS Marketplace, streamlining IoT project development. Designed to simplify the management of IoT initiatives for professionals and businesses, Arduino Cloud…
VNA boasts four independent RF sources
Part of Keysight’s PNA-X vector network analyzer portfolio, the NA520xA integrates up to four RF sources, two combiners, and two low-noise receivers. Its independent RF sources with pulse modulators and source filters eliminate the need for…
SiC MOSFETs target EV traction inverters
ST has launched its fourth-generation STPOWER SiC MOSFETs, offering smaller size and greater efficiency for future EV traction inverters. Set to be available in 750-V and 1200-V classes, these devices will enhance energy efficiency and performance…
Software eases embedded GUI development
The complimentary Microchip Graphics Suite (MGS) lets designers create sophisticated embedded GUIs for 32-bit MCUs and MPUs. Designed to easily integrate with Microchip’s broad portfolio 32-bit devices, MGS works with multiple development…
The power of practical positive feedback to perfect PRTDs
Frequent contributor Nick Cornford recently published a delightfully clever design idea using a platinum RTD calibrated to output a 1 mV/oC signal that’s perfect for direct readout via a standard DMM…
Wow the engineering world with your…
The Colpitts oscillator
Consider the following illustration in Figure 1 of what we shall see is an oscillator, specifically, a Colpitts oscillator.
