Calculating fudge factor (or electronic component de-rating)
Adding a “fudge factor” is actually a thing in engineering, but there’s a more formal-sounding name for it: de-rating. Both refer to the process of providing more robustness than is called for. There are many reasons for doing this. Sometimes new components are on the low side of average. For instance, electronics components are rated […]
Decoupling capacitor or bypass capacitors: why so many?
A capacitor behaves like an open circuit at DC voltages. (Recall that DC is voltage that operates at a frequency of 0 Hz, which is a flat-line voltage of varying heights or levels). If there’s an AC (varying) component or noise in the signals traveling in the circuit, then as the frequencies of the varying […]
Automation and robotics contest centers on Arduino platform
Arduino has today launched a global contest that challenges users of its open-source electronics platform to create innovative products that help advance the development of Industry 4.0 automation and robotics applications. The contest is being run in partnership with electronics and automation distributor Distrelec, and is hosted at the Arduino Project Hub. Contestants are required […]
Bluetooth Low Energy processors foster innovations in healthcare
Applications for fitness tracking and remote health monitoring have grown to such an extent that chip makers have developed SoCs optimized for counting heartbeats and calculating glucose levels. Steven Dean, ON Semiconductor Smart wearables for mobile health (mHealth) applications are an exciting area. They can monitor vital signs and drug delivery and then send data […]
Software-defined radio powers the IoT
ADCs with SDR help reduce design efforts and let designers focus on implementing more fashionable features. Ryan Liu | Microchip Technology Inc. Software-defined radio (SDR) technology finds its way into everything from multi-carrier multi-standby smartphones to innovative multi-mode mobile internet electronics. When enabled by SDR, a configurable transceiver works flexibly with software-defined carrier frequencies, easing […]
Core independent peripherals have zero dependence on CPUs…really?
The Core Independent Peripheral (CIP) is a term coined by Microchip Technology to describe an unusual control scheme whereby peripherals do not rely upon input from the Central Processing Unit (CPU). Microchip claims that these self-sustaining peripherals free up the CPU, increase power savings, reduce development time and are easily configured with Microchip graphical programming […]
How to create energy-efficient IIoT sensor nodes
by Noel O’Riordan and Tommy Mullane, S3 Semiconductors When you’re designing sensor node devices destined for the industrial internet of things (IIoT), chances are they need to be battery-powered. And given the number of these expected to be deployed, and their often-remote locations, changing or charging a battery frequently isn’t an option. Your device, therefore, needs […]
Review: Optimizing IoT battery life with the Otii
A handy gadget for analyzing current consumption helps shed light on how internet-of-things appliances can be optimized for energy efficiency. The Otii, from the Qiotech group in Sony Mobile Communications, is one of those ideas that seems obvious only after you’ve seen it. It targets developers who must minimize the current drain from batteries, a […]
