An eye diagram is a powerful visualization tool in digital communications and high-speed electronics to assess signal quality and channel performance. This FAQ will briefly explain an eye diagram and the overall and specific metrics engineers should know to understand an eye diagram. During a digital bitstream, many signals superposition over each other with multiple […]
Mitigate reverse recovery overshoot in MOSFET body diodes
Because of their compact size, higher efficiency, and superior performance in high-power applications, SiC MOSFETs are now replacing Si devices in switching applications. SiC devices enable faster switching times, significantly reducing switching losses. These advantages stem from the unique electrical and material properties of SiC-based devices — snappy reverse recovery inherent to the structure of […]
Bipolar junction transistors show their muscle
Recent enhancements to the classic BJT show that the classic transistor has plenty of life left and can challenge SiC and GaN devices in some power applications. Amidst the advances in CMOS and wide bandgap semiconductor technology, you can easily forget that the first transistor invented by William Shockley in 1949 was a bipolar junction […]
Ensuring integrity in high-performance interconnects with connector backshells
This article examines how modern backshell technologies contribute to high-performance interconnects’ electrical and mechanical integrity and some key factors to consider during the specification phase. Today’s aerospace, defense, and medical applications demand connectors that offer high-speed and compact interconnections, withstand vibrations and shocks, and maintain immunity against electromagnetic and RF interference (EMI/RFI). Achieving this requires […]
Building the quantum future: how to master quantum control design
By Udo Weiss and Christian Ganninger, nVent In quantum computing systems, control electronics are critical in facilitating the operation and manipulation of qubits. Their precision ensures the integrity and accuracy of quantum computing processing and results. Engineers need minimal latency in the low milliseconds to effectively operate their chassis, including switches and central processing unit […]
How do SiC and GaN devices age?
By Peter Friedrichs, Infineon Technologies SiC and GaN devices operate at higher stress levels than silicon devices. The semiconductor and automotive industries have strict qualification tests for that. Silicon carbide (SiC) and gallium nitride (GaN) wide bandgap (WBG) technologies are well known for their performance advantages over silicon (Si) in many high-power areas, including their […]
Selection and implementation of BLDC control strategy
By Shoa Zhang, Qorvo Understanding the differences between trapezoidal, sinusoidal, and field-oriented control can help engineers understand the value of Field Oriented Control (FOC) and the choices available to optimize their designs. BLDC motors can be smaller, lighter, and quieter than traditional brushed DC motors while enhancing the reliability and energy efficiency of consumer, industrial, […]
Verify, test, and troubleshoot 5G Wi-Fi FWA gateways
By Xiang Li, Keysight Technologies Follow these three steps to ensure your fixed-wireless access designs will be compatible with the Wi-Fi fronthaul and 5G backhaul. Many areas lack the wired infrastructure to bring residential broadband access. Making those connections has become costly and inefficient. Fixed Wireless Access (FWA) has emerged as a compelling alternative to […]
10Base-T1S simplifies automotive zonal architectures
By Andreas Pellkofer and Madhura Deyanda Poonacha, Analog Devices Automakers aim to provide vehicles with home-like comfort and entertainment, which raises demand for electronic control units (ECUs). Older bus technologies and electrical/electronic architectures struggle to keep up. 10Base-T1S Ethernet is transforming cars into fully connected experiences. Automotive electronic control units (ECUs), which control each component […]
Sensors in American football can help the game
By Anson Yeganegi and Song Li, InvenSense Sensors can improve player safety and performance through data collection. Both soccer and American football have embraced advanced technologies to varying degrees, including the use of sensors to elevate tracking and data collection in both games. The first sensor-enabled game ball using Connected Ball Technology, for instance, was […]
