Opportunities for electrically-propelled autonomous mobility and advanced automation continue to multiply in the quest for greater industrial productivity, smarter living, and increased energy efficiency. Encoders can play a large part in these applications as motors require precisely tracked position and motion. However, with multiple encoder types and communication protocols on the market, what are the […]
What do molded power inductors bring to high efficiency, compact designs?
Modern hardware applications trend towards compact designs that are power efficient. Passive devices don’t get as much attention as a microcontroller’s many sleep and shutdown states. However, every drop of available efficiency adds up and can make a difference. It’s possible to improve power efficiency with the right inductor. Power inductors are a necessary component […]
The fundamentals of MCU-based hardware virtualization
Virtualization, a powerful technology concept commonly associated with high-end applications in servers, is coming to the microcontrollers featuring multiple execution domains via multiple CPUs with a lock-step mechanism. The microcontrollers that incorporate hardware-based virtualization-assisted functions mark a new integration milestone in the embedded design world. Moreover, by running multiple software components on a single MCU […]
What matters for MCUs serving OTA functions in automotive designs
The technology features like over-the-air (OTA) software updates and data management are reinventing the hardware of today for the software of tomorrow. And if there is a single most prominent component at this technology crossroads, it’s the microcontroller. Moreover, the growing popularity of OTA functions is most visible in automotive environments where they wirelessly and […]
Vacuum tubes we still (have to) use: The traveling wave tube, Part 1
The previous parts of this article explored the photomultiplier tube (Part 1 and Part 2), which is based on a simple, fairly clear physics principle, although building a high-performance PMT is an art and requires various skills, of course. This part looks at a microwave/mm-wave amplifier called the traveling wave tube (TWT – often pronounced […]
Vacuum tubes we still (have to) use: The traveling wave tube, Part 2
We live in a world of solid-state active devices that have made most vacuum tubes obsolete, but a few types remain as they are still indispensable. The previous part of this article introduced the traveling wave tube and its basic operation, along with some attributes. This part delves into some related issues. Q: What’s the […]
What you need to know about MCUs for servo control
A servo motor, used for position feedback of angular rotation, applies pulse width modulation (PWM) signals for precise control over motion. Industrial design engineers can change the rotation angle and direction of the motor by varying the width of the PWM signal, and here, the role of MCU, which generates the PWM signal, inevitably becomes […]
Vacuum tubes we still (have to) use: The photomultiplier tube, Part 2
We live in a world of solid-state active devices that have made most vacuum tubes obsolete, but a few types remain as they are still indispensable. Part 1 of this article explained the basics of the photomultiplier tube. This part looks into other PMT characteristics. Q: Are there solid-state functional equivalents to the PMT? A: […]
Vacuum tubes we still (have to) use: The photomultiplier tube, Part 1
Maybe we can’t live with them, but we can’t live without them, at least not yet: the photomultiplier tube and the traveling wave tube are two vacuum electron-tube devices that are still viable and needed in our solid-state world.) It’s widely accepted conventional wisdom that almost “everything” has gone solid state and that vacuum tubes […]
How zero-touch provisioning simplifies IoT links to cloud
Zero-touch provisioning eliminates the manual labor needed to connect devices to a network and allows these devices to be provisioned and configured automatically. It’s especially critical for small and mid-size companies in terms of cost and time of managing the provisioning logistics. While it’s a common concept in the networking industry at large, MCU suppliers […]
