Deploying Accurate Always-On Face Unlock


Accurate face verification has long been considered a challenge due to the number of variables, ranging from lighting to pose and facial expression. This white paper looks at a new approach — combining classic and modern machine learning (deep learning) techniques — that achieves 98.36% accuracy, running efficiently on Arm ML-optimized platforms, and addressing key security issues such a... » read more

Modified X-Band Push-Push Oscillator Simulation And Measurement


This eBook that explores the push-push oscillator configuration via harmonic balance (HB) computer simulation and test measurement. The unique operation of the push-push oscillator configuration is explored using HB simulation of spectral content and time-domain voltage waveforms. Dynamic load lines are investigated and utilized to explore peak signal excursion and degree of nonlinearity. Predi... » read more

The Challenge Of Balancing Performance And Accuracy For Advanced Node Timing Signoff


As process nodes shrink, complexity, cost and overall risk expand. Process variability that once was once acceptable now becomes a critical item as operating voltage decreases. Simply adding design margin makes the chip non-competitive. Physical effects that were once ignored now become critical as well. The impact of interconnect can no longer be modeled based on simple circuit topology. Layou... » read more

Power/Performance Bits: Nov. 9


Integrated transistor cooling Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) created a single chip that combines a transistor and microfluidic cooling system for more efficient transistor heat management. The team focused on a co-design approach for the electrical and mechanical aspects of the chip, bringing the electronics and cooling design together and aiming to extract... » read more

Comprehensive Simulation Of Power Electronics Systems


Power electronics systems are at the heart of many important and growing industries, from all-electric vehicles to renewable energy generation. Optimizing the design of these systems requires accurate modeling and simulation long before construction of physical prototypes. SPICE-level simulation has been the traditional solution and, while it still plays a key role, it cannot satisfy all requir... » read more

Power/Performance Bits: Nov. 3


Wirelessly charging multiple devices Researchers from ITMO University developed a metamaterial that can be used to turn surfaces into wireless charging areas for multiple devices from different manufacturers with different power transfer standards. "There are various wireless power transfer standards with different frequencies, so you can't just use a charger by any manufacturer," said Poli... » read more

Performance and Power Tradeoffs At 7/5nm


Semiconductor Engineering sat down to discuss power optimization with Oliver King, CTO at Moortec; João Geada, chief technologist at Ansys; Dino Toffolon, senior vice president of engineering at Synopsys; Bryan Bowyer, director of engineering at Mentor, a Siemens Business; Kiran Burli, senior director of marketing for Arm's Physical Design Group; Kam Kittrell, senior product management group d... » read more

Power/Performance Bits: Oct. 27


Room-temp superconductivity Researchers at the University of Rochester, University of Nevada Las Vegas, and Intel created a material with superconducting properties at room temperature, the first time this has been observed. The researchers combined hydrogen with carbon and sulfur to photochemically synthesize simple organic-derived carbonaceous sulfur hydride in a diamond anvil cell, which... » read more

Power/Performance Bits: Oct. 20


Benchmarking quantum layout synthesis Computer scientists at the University of California Los Angeles found that current compilers for quantum computers are inhibiting optimal performance and argue that better quantum compilation design could help improve computation speeds up to 45 times. The team designed a family of benchmark quantum circuits with known optimal depths or sizes, which cou... » read more

Increase In Analog Problems


Analog and mixed signal design has always been tough, but a resent survey suggests that the industry has seen significantly increased failures in the past year because the analog circuitry within an ASIC was out of tolerance. What is causing this spike in failures? Is it just a glitch in the data, or are these problems real? The answer is complicated, and to a large extent it depends heavily... » read more
