Dynamic Control of Synaptic Plasticity by Competing Ferroelectric and Trap‐Assisted Switching in IGZO Transistors with Al2O3/HfO2 Dielectrics

Advanced Functional Materials, EarlyView.
A frequency‐tunable ferroelectric synaptic transistor based on a buried‐gate InGaZnO channel and Al2O3/HfO2 dielectric stack exhibits linear and reversible weight updates using single‐polarity pulses. By switching between ferroelectric and trap‐assisted modes depending on input frequency, the device simplifies neuromorphic circuit design and achieves ...

Implementation of sub-nanosecond time-to-digital convertor in field-programmable gate array: applications to time-of-flight analysis in muon radiography [PDF]

, 2013
Time-of-flight (TOF) techniques are standard techniques in high energy physics to determine particles’ propagation directions. Since particle velocities are generally close to c, the speed of light, and detector typical dimensions at the metre level, the

Efficient Addition on Field Programmable Gate Arrays [PDF]

, 2001
We investigate average efficient adders for grid-based environments related to current Field Programmable Gate Arrays (FPGAs) and VLSI-circuits. Motivated by current trends in FPGA hardware design we introduce a new computational model, called the λ -wired grid model. The parameter λ describes the degree of connectivity of the underlying hardware. This

An FPGA Architecture for Extracting Real-Time Zernike Coefficients from Measured Phase Gradients

Measurement Science Review, 2015
Zernike modes are commonly used in adaptive optics systems to represent optical wavefronts. However, real-time calculation of Zernike modes is time consuming due to two factors: the large factorial components in the radial polynomials used to define them
