(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 ... -
Low-noise Amplifier for Neural Recording
(University of Waterloo, 2015-10-30)With a combination of engineering approaches and neurophysiological knowledge of the central nervous system, a new generation of medical devices is being developed to link groups of neurons with microelectronic systems. ... -
Low-Power and High-Performance Drivers for OLEDoS Microdisplays
(University of Waterloo, 2023-09-19)The rapid growth of the microdisplay market, driven by the demand for smartwatches, head-mounted displays in Virtual Reality (VR) and Augmented Reality (AR), and other portable devices, has presented a need to enhance their ... -
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 ... -
