A new software combines connectivity, scalability and data-driven artificial intelligence (AI) capabilities to push the boundaries of the IC verification process and make chip design teams more productive. Questa One aims to address the verification productivity gap for large, complex designs spanning IP to IC to systems.

In April 2012, EDN published a circuit by John Fattaruso that lets you quickly measure the drain-source saturation current and the pinch-off voltage of both an N-JFET and a P-JFET. The pinch-off voltage (Vp) is measured by inserting a very large resistance between the source and the ground. The drain-source saturation current (IDSS) is measured by inserting a small resistance between the source and the ground.

Bluetooth channel sounding—a new protocol stack designed to enable secure and precise distance measurement between two Bluetooth Low Energy (LE) devices—is propelling Bluetooth technology into a new era of location awareness. It offers true distance awareness while enhancing Bluetooth devices’ ranging capabilities. Bluetooth channel sounding’s use spans from helping locate devices such as phones or tablets to digital security enhancements like geofencing.

Quantum computers are among today’s most exciting emerging technologies, but their design, testing, and manufacturing require unparalleled care to avoid damaging their components. Semiconductors are sensitive, so they require production environments with minimal contamination risks. Cleanrooms are the industry-standard solution, but even these facilities must reach higher standards for quantum computer development.

CoolSiC JFETs from Infineon provide low conduction losses and robust turn-off behavior for solid-state protection and power distribution. Their strong short-circuit capability, linear-mode thermal stability, and accurate overvoltage control make them well-suited for solid-state circuit breakers, automotive battery disconnect switches, and industrial safety relays. The bulk-channel optimized JFETs offer RDS(on) values as low as 1.5 mΩ for 750 V devices and 2.3 mΩ for 1200 V variants.
