Low-Dimensional Nanostructured Catalysts of Copper Oxides and Nickel Oxides Supported on Graphene and Their Applications in Biosensing and Photoelectrochemical Hydrogen Evolution
(University of Waterloo, 2024-01-22)Cuprous oxide (Cu2O) nanomaterials provide a versatile platform for building non-enzymatic glucose sensors. In particular, Cu2O nanocubes with controllable sizes and distributions can be deposited electrochemically on a ... -
Low-Frequency Electromagnetic Energy Harvesting
(University of Waterloo, 2012-01-03)The demand for portable permanent sources of electrical energy increases every day to power portable or non-accessible devices. Energy harvesting from vibrations offers a non-traditional source of energy. It is renewable ... -
Low-Frequency Piezoelectric Energy Harvester with Novel 3D Folded Zigzag Design and High Power Density
(University of Waterloo, 2018-07-09)Cantilevers have been widely used for vibration energy harvesting applications using piezoelectric materials due to their simple geometries, frequency tune-ability, and closed form analytical solution. Recent studies have ... -
Low-Leakage ESD Power Supply Clamps in General Purpose 65 nm CMOS Technology
(University of Waterloo, 2017-01-20)Electrostatic discharge (ESD) is a well-known contributor that reduces the reliability and yield of the integrated circuits (ICs). As ICs become more complex, they are increasingly susceptible to such failures due to the ... -

A low-power dynamic comparator for low-offset applications
(Elsevier, 2019-11)In this paper, a low-power method for double-tail comparators is introduced. Using the proposed method, the power consumption of the pre-amplifier which is the dominant part is reduced considerably. Thanks to this method, ... -
Low-Power High-Performance Ternary Content Addressable Memory Circuits
(University of Waterloo, 2006)Ternary content addressable memories (TCAMs) are hardware-based parallel lookup tables with bit-level masking capability. They are attractive for applications such as packet forwarding and classification in network ... -
Low-Power Soft-Error-Robust Embedded SRAM
(University of Waterloo, 2013-01-08)Soft errors are radiation-induced ionization events (induced by energetic particles like alpha particles, cosmic neutron, etc.) that cause transient errors in integrated circuits. The circuit can always recover from such ... -
Low-Power, Low-Voltage SRAM Circuits Design For Nanometric CMOS Technologies
(University of Waterloo, 2011-08-30)Embedded SRAM memory is a vital component in modern SoCs. More than 80% of the System-on-Chip (SoC) die area is often occupied by SRAM arrays. As such, system reliability and yield is largely governed by the SRAM's performance ... -
Low-Rank Plus Sparse Decompositions of Large-Scale Matrices via Semidefinite Optimization
(University of Waterloo, 2023-05-19)We study the problem of decomposing a symmetric matrix into the sum of a low-rank symmetric positive semidefinite matrix and a tridiagonal matrix, and a relaxation which looks for symmetric positive semidefinite matrices ... -
LOW-RESOLUTION CUSTOMIZABLE UBIQUITOUS DISPLAYS
(University of Waterloo, 2023-09-22)In a conventional display, pixels are constrained within the rectangular or circular boundaries of the device. This thesis explores moving pixels from a screen into the surrounding environment to form ubiquitous displays. ... -
Low-temperature characterization of dielectric loss at microwave frequencies in aluminum oxide
(University of Waterloo, 2015-04-09)Superconducting quantum devices have gained increasing interest over the past 15 years because of their role as promising candidates for implementing a large-scale quantum computer and as ultra-sensitive detectors. ... -
A lower bound for the two-variable Artin conjecture and prime divisors of recurrence sequences
(Elsevier, 2019-01-01)In 1927, Artin conjectured that any integer other than −1 or a perfect square generates the multiplicative group (Z/pZ)× for infinitely many p. In 2000, Moree and Stevenhagen considered a two-variable version of this ... -
Lower Bounds and Derandomization
(University of Waterloo, 2008-08-26)A major open problem in complexity theory is to determine whether randomized complexity classes such as BPP, AM, and MA have any nontrivial derandomization. This thesis investigates the derandomization of two randomized ... -
Lower Bounds on Quantum Query and Learning Graph Complexities
