How SiC turbocharges EV infrastructure building blocks
Designers of automotive subsystems constantly strive to develop innovative solutions to extend the range and reduce the charging time of electric vehicles (EVs). In the pursuit of these goals, they have pushed silicon-based technologies close…
How BAW addresses spectrum coexistence challenges in Wi-Fi 7
The transition from Wi-Fi 6 to Wi-Fi 7 has been a game changer, more than doubling the available frequency for wireless network. Traditionally, Wi-Fi has used the 2.4 GHz or 5 GHz super high frequency (SHF) radio bands. But Wi-Fi 7 introduces…
Carrier links Arduino Pro with Raspberry Pi
Arduino Pro’s Portenta Hat Carrier transforms the Portenta system-on-module (SOM) into an industrial single-board computer using Raspberry Pi Hats. Outfitted with a Raspberry Pi-compatible 40-pin header, the carrier board provides access to…
Image sensor excels in difficult lighting
With improved sensitivity and minimized readout noise, Omnivision’s OS08C10 8-Mpixel image sensor is well-suited for home and professional security cameras. The sensor provides both staggered high dynamic range (HDR) and single-exposure dual…
Inductive position sensor achieves high resolution
Renesas has developed an inductive position sensor (IPS) technology that delivers a resolution of up to 19 bits and accuracy of up to 14 bits. The magnet-free, dual-coil technology can replace magnetic and optical encoders used in motor control…
Optical network chips power home gateway units
Gemtek has selected MaxLinear’s PRX 10G passive optical network (PON) chips for its mid-market Wi-Fi 6 AX3000 PON home gateway units (HGUs). In addition to the PRX series G-PON and XGS-PON devices, the HGUs integrate MaxLinear’s Wi-Fi 6…
Spectrum analyzer identifies uplink interference
Software for Anritsu’s Field Master spectrum analyzer performs uplink interference measurements in 5G and LTE time division duplexing (TDD) networks. This measurement is now included in the analyzer’s 5G and LTE measurement options. It provides…
Toward better behaved Sallen-Key low pass filters
The most common type of filter is probably the low pass. Among active filters, the Sallen-Key is the most widely used topology (Figure 1).
Figure 1 A first order op-amp-based Sallen-Key low-pass filter with broadband gain 1+Rf0/Rg0.
Wow the…
3-leg regulator in shunt mode makes variable power supply symmetrical
Surprising facts, like “old fangled” 3-leg linear regulators (LM317, LM337, LM350, et al) can be used in shunt regulator topologies and can sometimes inspire “new, fangled” circuit designs. Figure 1 shows a useful example.
Figure 1 Symmetrical-output…
Layoffs at SiFive as RISC-V upstart faces a crossroads
SiFive, a prominent player in the RISC-V design arena, is going through a radical makeup. While layoffs at one of the early RISC-V startups are making headlines in trade media, what’s happening underneath is a significant shift in its business…
Power Tips #122: Overview of a planar transformer used in a 1-kW high-density LLC power module
Growing data center power demands are driving server equipment manufacturers to reach higher power-conversion efficiencies in order to reduce the thermal footprint of their systems. The transition from a 12-V power distribution bus to a 48-V…
RISC-V Tensor Unit claims to turbocharge AI applications
A new RISC-V Tensor Unit, based on fully customizable 64-bit cores, claims to provide a huge performance boost for artificial intelligence (AI) applications compared to just running software on scalar processors. The Tensor Unit provides matrix…
