Ultra-Low Resonance Frequency MEMS Gravimeter With Off-Resonance Closed-Loop Control
By Coventor - 16 Jun, 2022 - Comments: 0

This paper reports on a MEMS gravimeter that has a closed-loop system to maintain an ultra-low resonance frequency of 1Hz. The low resonance frequency is attained by using a spring that is the resultant of positive mechanical stiffnesses and negative electrical stiffnesses. Voltage-tunability of the electrical stiffness enables ultra-small and tunable total stiffness. To attain a quick response... » read more

Research Bits: June 14
By Jesse Allen - 14 Jun, 2022 - Comments: 0

Photonic deep neural network chip Engineers from the University of Pennsylvania built a photonic deep neural network on a 9.3 square millimeter chip they say is faster and more efficient at classifying images, with the ability to process nearly two billion images a second. The chip uses a series of waveguides that form 'neutron layers' mimicking the brain. “Our chip processes information ... » read more

U. Of Florida: Protecting Chip-Design IP From Reverse-Engineering
By Technical Paper Link - 13 Jun, 2022 - Comments: 0

New research paper titled "Hardening Circuit-Design IP Against Reverse-Engineering Attacks" from University of Florida. "Design-hiding techniques are a central piece of academic and industrial efforts to protect electronic circuits from being reverse-engineered. However, these techniques have lacked a principled foundation to guide their design and security evaluation, leading to a long line... » read more
