Ring Amplifiers for Switched Capacitor Circuits

Creator:: Hershberg, Benjamin, Weaver, Skyler, Sobue, Kazuki, Takeuchi, Seiji, Hamashita, Koichi, and Moon, Un-Ku
Abstract:: In this paper the fundamental concept of ring amplification is introduced and explored. Ring amplifiers enable efficient amplification in scaled environments, and possess the benefits of efficient slew-based charging, rapid stabilization, compression-immunity (inherent rail-to-rail output swing), and performance that scales with process technology. A basic operational theory is established, and...

Ocean wavenumber estimation from wave-resolving time series imagery

Creator:: Plant, Nathaniel G., Holland, K. Todd, and Haller, Merrick C.
Abstract:: We review several approaches that have been used to estimate ocean surface gravity wavenumbers from wave-resolving remotely sensed image sequences. Two fundamentally different approaches that utilize these data exist. A power spectral density approach identifies wavenumbers where image intensity variance is maximized. Alternatively, a cross-spectral correlation approach identifies wavenumbers where...

An overview of MODIS capabilities for ocean science observations

Creator:: Esaias, Wayne E., Abbott, Mark R., Barton, Ian, Brown, Otis B., Campbell, Janet W., Carder, Kendall L., Clark, Dennis K., Evans, Robert H., Hoge, Frank E., Gordon, Howard R., Balch, William M., Letelier, Richard, and Minnett, Peter J.
Abstract:: The Moderate Resolution Imaging Spectroradiometer (MODIS) will add a significant new capability for investigating the 70% of the Earth's surface that is covered by oceans, in addition to contributing to the continuation of a decadal scale time series necessary for climate change assessment in the oceans. Sensor capabilities of particular...

A Continuous-Time Delta-Sigma Modulator for Biomedical Ultrasound Beamformer Using Digital ELD Compensation and FIR Feedback

Creator:: Zhang, Yi, Chen, Chia-Hung, He, Tao, and Temes, Gabor C.
Abstract:: This paper presents the design of a continuous-time ΔΣ modulator (CTDSM) to be used in an ultrasound beamformer for biomedical imaging. To achieve better resolution, the prototype modulator operates at 1.2 GHz. It incorporates a digital excess loop delay (ELD) compensation to replace the active adder in front of the...

A cardiovascular prosthesis for subhuman primates

Creator:: Chambers, Alan B.
Abstract:: This study reports the design, construction, and evaluation of an automatic cardiac massage device and support system. The design incorporates the principle of a cardioplethysmograph operated in reverse, such that pneumatic power fed to the prosthesis will mechanically impart a massaging action to the heart. Basically, the prosthesis is a...

Efficient Deep Learning Methods for Biomedical Applications

Creator:: Thota, Narayana Bhagirath
Abstract:: Deep Learning methods have been gaining a lot of significance for various Biomedical applications for diagnosing several types of diseases. Two applications considered here are: 1) Diabetic Retinopathy Detection and 2) ECG signal Classification (or Arrhythmia Detection). Diabetic Retinopathy (DR) is a major cause of blindness in Diabetic patients, and...

Reversible Covalent Immobilization of Desferrioxamine B (DFOB) on Aminated Polystyrene Beads for Citrate-Bound Fe(III) Chelation

Creator:: Touma, Jad G.
Abstract:: The immobilization of chelators to solid supports has recently gained renewed interest due to the increasing biomedical and environmental applications made possible by these molecules’ ability to bind Fe(III) and other metal ions. The uses of immobilized chelators have expanded to include the treatment of metal overload in serum, the...
