Spark taps Infineon for wireless charging module
The Yeti 500W industrial wireless charging module from Spark Connected employs Infineon’s dual-core PSoC Bluetooth Low Energy MCU for intelligent control. It also incorporates Infineon’s CoolGaN power devices for improved efficiency and…
1kHz per degree Kelvin temperature sensor
Long ago in a galaxy far away (actually, the same galaxy but the Milky Way is moving so it must logically be far away from where it was way back then), I sketched up a simple circuit for a DC coupled amplifier that I thought (in my youthful…
Power Tips #120: How isolated bias transformer parasitic capacitance impacts EMI performance
Small, isolated power supplies provide power across isolation barriers in applications from electric vehicle traction inverters to factory control modules. In this Power Tip, I’ll examine different isolated bias-supply topologies and their…
The commercialization of digital circuit breakers
Ryan Kennedy began his career as an electrician, and after spending six years in the power distribution industry, he went to college to become a professional engineer. During his college days and soon after that, Kennedy worked on building designs,…
Two-half-period rectifiers on op amps
Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken from the output of the zero-indicator made…
Edge and corner cases: AI’s conceptual simplifications and potential complications
Whether or not (and if so, how) to account for rarely encountered implementation variables and combinations in hardware and/or software development projects is a key (albeit often minimized, if not completely overlooked) “bread and butter”…
A sneak peek at next-generation ultrasound imaging
The use of sound waves for non-invasively visualizing a fetus in the womb, via ultrasound imaging, is widely recognized. By emitting high-frequency sound waves into the body and converting their echo into electrical signals, real-time images…
Why responsible implementation of AI technology is critical
Artificial intelligence (AI) is seemingly everywhere. As AI models like ChatGPT are experiencing a meteoric rise in popularity, calls from critics and regulators have circulated the airwaves to do something about the potential threats that AI…
Partnership elevates video doorbell security
Omnivision and iCatch Technology are working together to bring enhanced color pre-roll and edge AI processing to wireless home security products. With pre-roll enabled, users can save up to 4 seconds of video footage prior to the camera’s…
Optical sensor improves performance, shrinks footprint
A reflective optical sensor, the VCNT2030 from Vishay provides a high current transfer ratio (CTR) and increased sensing distance in a tiny surface-mount package. The VCNT2030 packs a vertical-cavity surface-emitting laser (VCSEL) and silicon…
PIN diode switches operate up to 75 GHz
Comprising 10 models, Pasternack’s line of ultra-broadband PIN diode switches covers frequencies ranging from 1 MHz to 75 GHz. The military-grade devices are available in SP2T, SP4T, and SP8T configurations, all with integrated TTL drivers…
Kyocera-AVX launches supercapacitor modules
Series-connected supercapacitor modules in the SCM series from Kyocera-AVX provide strong pulse power handling with high capacitance and low ESR. The double-layer, electrochemical supercapacitor modules can be used by themselves or in conjunction…
