Microwave Photonic Pulse Generation With High Transfer Rate and Precision Pulse Width by Partly Temporally-Overlapped Photon Echo Excitation

open access: yesIEEE Photonics Journal, 2022
Microwave photonic pulse generation has intrinsic high speed and large bandwidth, and it can overcome the sampling-rate limitation in the electrical domain. Herein, we propose a partly temporally-overlapped photon echo scheme to generate microwave pulses

Electric Circuit Realizations of Fracton Physics [PDF]

open access: yesPhys. Rev. B 100, 245103 (2019), 2019
We design a set of classical macroscopic electric circuits in which charge exhibits the mobility restrictions of fracton quasiparticles. The crucial ingredient in these circuits is a transformer, which induces currents between pairs of adjacent wires. For an appropriately designed geometry, this induction serves to enforce conservation of dipole moment.

Nonlinearity and Domain Switching in a 3D‐Printed Architected Ferroelectric

open access: yesAdvanced Engineering Materials, EarlyView.
By combining functional properties measurement with in situ 2D X‐ray microdiffraction experiments, it is shown that nonlinear polarization and strain responses of a 3D‐printed architected ferroelectric are driven by localized progression of domain switching, which depends on nonuniform electric‐field distribution as well as evolving stress fields.

An improved kT/C noise cancellation technique with presampling for high‐speed SAR ADCs

open access: yesElectronics Letters
The kT/C noise cancellation technique can effectively reduce the digital‐to‐analog converter (DAC) size for successive approximation register ADCs and thus relax the burden for input drivers and reference buffers.

Single-structure 3-axis Lorentz force magnetometer based on an AlN-on-Si MEMS resonator

open access: yesMicrosystems & Nanoengineering
This work presents a single-structure 3-axis Lorentz force magnetometer (LFM) based on an AlN-on-Si MEMS resonator. The operation of the proposed LFM relies on the flexible manipulation of applied excitation currents in different directions and ...

Notes on Hazard-Free Circuits [PDF]

open access: yesarXiv, 2020
The problem of constructing hazard-free Boolean circuits (those avoiding electronic glitches) dates back to the 1940s and is an important problem in circuit design and even in cybersecurity. We show that a DeMorgan circuit is hazard-free if and only if the circuit produces (purely syntactically) all prime implicants as well as all prime implicates of ...
