Low Noise, Low Power Capacitive-Coupling Quadrature Voltage-Controlled Oscillator for Phase-Locked Loops
(2012-11-06)
This dissertation presents the analytical results and design details of two quadrature voltage-controlled oscillators (QVCO). It uses capacitive quadrature-coupling technique to couple two voltage-controlled oscillator ...
Low Phase Noise Voltage-Controlled Oscillators for Wide-Band Frequency Synthesis
(2013-11-11)
Noise-bandwidth trade-off is a challenge issue in modern voltage-controlled oscillator (VCO) designs. Wide-tuning VCOs usually suffer degraded phase noise. A mixer based tuning range enhancement technology is proposed in ...
A Low Power 10 GHz Phase Locked Loop for Radar Applications Implemented in 0.13 um SiGe Technology
(2009-04-14)
In today's society there is a growing trend where microwave wireless devices are becom-
ing common in every household and workplace. The increasing desire for these devices is to
create smaller low power devices. There ...
A Low Power, Low Noise Phase Locked Loop MMIC for Ku- and X-Band Applications
(2009-03-23)
This paper presents the analysis, design, simulation, and test results for a Fractional-N
PLL frequency synthesizer. The synthesizer is designed to cover multiple frequency bands,
require low power, and have low noise. ...
Low Speed Orthogonal Hot Machining With a Virtual Quick Stop Device
(2016-05-06)
Cocquilhat first documented (1851) how heat in a tool shortens the life of the tool. Research since his time has generally concluded that the tool gives up a relatively higher percentage of its “cold hardness and toughness” ...
Low Temperature Modeling of I-V Characteristics and RF Small Signal Parameters of SiGe HBTs
(2009-11-11)
SiGe HBT has been attached great attention recently to be used for space exploration due to its high-quality performance compared with conventional Si bipolar transistor over an extremely wide temperature range. The ...
Low Temperature Oxidation of Carbon Monoxide Using Microfibrous Entrapped Catalysts for Fire Escape Mask Application
(2005-08-15)
The prime reason for life casualties in fire is not the fire itself but poisoning caused by presence of carbon monoxide. It has been reported by American Medical Association that CO causes about 2100 deaths per year and ...
Low-Bandwidth Three Dimensional Mapping and Latency Reducing Model Prediction to Improve Teleoperation of Robotic Vehicles
(2012-07-25)
This thesis uses novel three dimensional sensors like the Microsoft Kinect [1] and the Asus Xtion Pro Live [2] to generate three dimensional environments and use the recon- structed environment with a predictive model in ...
Low-Cost, Rapid, Sensitive Detection of Pathogenic Bacteria Using Phage-Based Magnetoelastic Biosensors
(2013-04-05)
As part of the ongoing efforts to secure food safety as well as to guard against possible bioterrorism, the role of pathogen detection technologies has become vital. However, conventional and standard detection methods, ...
Low-dose clozapine but not haloperidol attenuates ketamine-induced deficits under an incremental repeated acquisition procedure
(2014-08-07)
Ketamine, like other N-methyl-D-aspartate (NMDA) receptor antagonists, causes both locomotor and cognitive dysfunction, decrements that may be mediated by distinct neurotransmitter systems. The present study was designed ...
A Low-Effort Animated Data Structure Visualization Creation System
(2014-07-09)
Algorithm animations and high level data structure visualizations are not widely used, in part because producing them is difficult and time consuming. Algorithm animation and data structure visualization systems attempt ...
A Low-Power Analog Bus for On-Chip Digital Communication
(2013-07-10)
At present, performance and efficiency of a system-on-chip (SoC) design depends significantly on the on-chip global communication across various modules on the chip. On-chip communication is mostly implemented using a bus ...
Low-Power, High-Performance Frequency Dividers for a Phase-Locked Loop
(2020-03-16)
The world embraces the dawn of 5G implementation, and there is much work to be done. Companies, researchers, engineers, and many more posterities of people are pressing into high-frequency ranges, which presents a plethora ...
Low-Slip Force Friction Connections for Early Phase Energy Dissipation in Steel Structures
(2015-11-10)
Previous research suggests adding early phase energy dissipation to structural steel systems can improve seismic performance. This can be achieved with a Low-slip Force Friction (LSFF) damper designed to activate prior to ...
Lower Bounds for Betti Numbers in Vietoris–Rips Complexes of Hypercubes
(2024-04-29)
