A fully integrated CMOS GPS receiver RF front end optimized for low power operation is presented. The system operates with a supply voltage down to 250 mV. A prototype has been fabricated in a 0.13μm CMOS process and includes a low voltage LNA, quadrature oscillators, and quadrature mixers. It exhibits...
This qualitative study examines how FIESTAS (Family Involved in Education, Sociocultural Teaching and STEM) partners (comprised of out-of-school time (OST) educators, university student STEM instructors, and local business representatives) came together to facilitate a local STEM Club located in two dual-immersion elementary schools in the Pacific Northwest. The study addresses...
In regards to animation created and aimed at them, girls are largely underserved and underrepresented. This underrepresentation leads to decreased socio-cultural capital in adulthood and a feeling of sacrificed childhood. Although there is a common consensus in entertainment toward girls as a potentially deficient audience, philosophy and applied ethics open...
A new comprehensive wide-band compact modeling methodology for single-ended spiral inductors and differential spiral inductors is presented. The new modeling methodology creates an equivalent circuit model consisting of frequency-independent circuit elements for use in circuit simulators. A fast automated extraction procedure is developed for determining the circuit element values from...
Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...
To understand mechanisms linking ecosystem processes and microbial diversity in freshwater ecosystems, bacterial productivity and the metacommunity dynamics of species sorting and mass effects were investigated in an 18 ha headwater lake in northern Alaska. On most sampling dates, the phylogenetic composition of bacterial communities in inflowing streams (inlets) was...
