IoT Systems Need High Integration and Small Form Factor Power Conversion Devices

At the medium-to-low end of the power spectrum, there are modest power conversion requirements, such as those commonly found in Internet of Things (IoT) equipment, that necessitate the use of power conversion ICs that deal with modest levels of current.

Improved charge balance A/D converter for load cell signal measurements

The charge balance analogue-to-digital (A/D) converter is a well-known high accuracy device, widely used in load cells measurement circuits; a load cell is a transducer which outputs an electrical signal with a magnitude directly proportional to the force being measured.

Shrinking electronics overtakes AI, 5G and the IoT as top electronics design trend for 2019

From artificial intelligence (AI) hardware to 5G standardisation, advancements in edge computing to the Internet of Things (IoT), 2018 was a year of bold technology promises. Looking back at 2018, we can evaluate which technology trend was worth the wait, and which was just hype.

Resonator-based metamaterial sensor for detecting unknown materials

Manmade composite materials with properties not usually found in nature, such as a negative refractive index for example, are called metamaterials.

Q&A with Duane Benson, CTO of Screaming Circuits, who discusses his technology predictions for 2019 and beyond

Duane Benson, Chief Technology Officer (CTO) at Screaming Circuits, a division of Milwaukee Electronics, discusses his technology predictions for 2019 – and beyond.

Miniature solar panels are being embedded in clothing to charge cellphones and wearables

Nottingham Trent University has found a way to embed miniaturised solar cells into yarn that can be knitted and woven into textiles.

French researchers develop new mass-spectrometry technology to tackle previously impossible tasks

A team of French researchers has demonstrated a new mass-spectrometry technology based on nanomechanical resonators that measures the mass of particles previously beyond the reach of current commercial technology. They then used their solution to measure the mass of a whole bacteriophage virus capsid, which has not been achieved before.

New T model Incorporating Conductor and Substrate Parasitic Losses for On-chip Transformers

The demand for low-power, low-cost and high-integration wireless communication systems is driving the development of on-chip passive devices for radio frequency integrated circuits (RFICs).

Integrated bidirectional bridge with dual RMS detectors for RF power and return-loss measurement

Directional couplers are used in many applications to sense RF power and may appear at multiple points in a signal chain.

Improved phase locked loop method for grid synchronisation of wind energy systems

Fossil-based energy sources have had significantly influenced human life, but not always positively, considering their impact on the climate.
