Part 1 of this blog addressed current shunts and Hall-effect sensor designs. This part discusses current transformers and new technology options such as magnetoresistance and even diamond quantum sensors. One of the major issues in today’s electric vehicles (EVs) is the ongoing evolution of technology with the standards evolving as well. In the 100+ years […]

What is the heterogeneous integration roadmap, and how does it support generative AI?
The heterogeneous integration roadmap (HIR) is an ongoing initiative of the IEEE Electronics Packaging Society. It’s a living document that continues to evolve and expand in response to technological developments like the growth of generative artificial intelligence (AI) and quantum computing. This FAQ starts with a brief overview of heterogeneous integration, looks at the scope […]
How current sensing impacts electric vehicles: part 1
The need to transition from gasoline and diesel (fossil fuels) powered vehicles to electric vehicles (EVs) to reduce carbon dioxide levels has revealed many controversial issues. Common issues include implementation timing, required infrastructure (including fast charging multi-vehicle systems), legislated rather than consumer-based adoption, ongoing system enhancements, and sources of new critical raw materials. One of […]
How to separate differential and common-mode harmonic noise currents
Differential-mode and common-mode currents can cause your product to produce radiated and conducted emissions. These three techniques can help you measure them.
How does the open domain-specific architecture relate to chiplets and generative AI?
The Open Domain-Specific Architecture (ODSA) is a project within the Open Compute Project (OCP) community to establish open physical and logical die-to-die (D2D) interfaces for chiplets. The goal is to democratize the design and use of chiplets for domain-specific high-performance computing (HPC) applications like generative artificial intelligence (AI). Domain-specific architectures (DSAs) are an emerging approach […]
How do heterogeneous integration and chiplets support generative AI?
Chiplets are here, and more are coming. They can overcome the yield limitations of large ASICs, support a mix-and-match strategy for heterogeneous semiconductor IPs and multiple process nodes, improve thermal performance, and speed time to market. They are being used in a range of high-performance computing (HPC) applications, notably generative artificial intelligence (AI) and machine […]
6G could add sensing to cellular networks
Integrated communications and sensing at mmWave and sub-THz frequencies could add location detection that helps avoid accidents among pedestrians, bicycles, and vehicles.
What quantum sensors can be used as GPS replacements?
There’s a variety of quantum sensors available for use as a global positioning system (GPS) replacement including quantum compasses, atomic gyroscopes, and atom interferometers. Several options for a quantum GPS replacement, also called quantum position sensing (QPS), are being developed. Three examples include quantum active navigation that overlays and supplements existing satellite-based GPS systems, quantum […]
How to raise awareness for the necessity of carbon monoxide sensors
Public outcries for reducing carbon dioxide (CO2) emissions to reduce their climate change impact have been widely promoted for more than two decades. However, attention to a more immediate public health problem from carbon monoxide (CO) has not received anywhere near the same level of attention– unless the deaths get news covered. For example, in […]
Passive RFID finds unanticipated mass-market applications: part 2
Passive RFID tags have been widely adopted, and some applications show creative adaptation to unmet needs. While many uses for passive RFID tags were predicted and expected, innovators implemented some that were not obvious. This part will look at two of those applications. Clothing-store “mass” checkout One obvious application predicted for passive RFID labels was […]
