Sponsored by Texas Instruments: Pushing beyond the superheterodyne, direct-sampling receivers can help meet the demands of today’s communications systems, but they need ultra-fast ADCs to make them work. Such converters have now arrived.
Developed by Microchip Technology, this “self-correcting” component features low initial offset voltage and drift, very low noise, and integral electromagnetic-interference filtering.
“Repaired, then over-repaired, until I broke it for good.” How did this solution eventually lead to dissolution? According to Paul Rako, the laser pointer took too much of a “beading.”
For decades, Advanced Micro Devices, the world's second largest maker of computer and graphics chips, manufactured all the chips it designed. But in 2008, AMD divested from its manufacturing operations, forming Globalfoundries in the process. As...
Allegro Microsystems introduced a line of motor drivers with integrated control algorithms, which could potentially curb costs and time-to-market for customers. The motor drivers contain field-oriented control—more commonly called FOC—algorithms...
Using a MEMS-based parallel-plate capacitor arrangement, NIST researchers devised a way to measure mid-range laser power via the radiation pressure exerted on the mirrored top plate and the resulting change in capacitance between plates.
Maxim Integrated introduced a line of chips that act as security supervisors for embedded devices, encrypting data for the central processor while preventing physical tampering with the device. The Silicon Valley company aims to make it...
By sensing optical-parameter shifts in a microresonator stimulated by a laser, a research team devised and tested a way to measure small changes in temperature with an EMI-resistant arrangement.
