The finite, electrostatically achievable, temporal resolution of plasma properties from a turbulent discharge is limited by an array of effects wherein the theory of Langmuir probes breaks down. Formulations for the particle transit time, sheath formation time, plasma-probe resonance, polarization current, sheath capacitance, stray capacitance, and mutual capacitance effects are all evaluated f...

This article presents a novel front-end circuit for remote grounded capacitive sensors. The is insensitive to amplifier input capacitance and stray interconnecting-cable capacitances. It does not rely on neutralization or compensation techniques that require manual adjustments high-accuracy reference components. proposed solution reduces the below few femptofarads using simple but properly shie...

This paper proposes an equivalent circuit model to obtain the transient electrical stress quantitatively in medium voltage frequency transformers modern power electronics. To verify this model, simulation is performed on a 1.5 kV/1 kHz transformer, revealing overshoot between turns and layers of transformer’s HV winding. Effects rise time input pulse voltage, stray capacitance winding insulatio...

Wide-bandgap technology evolution compels the advancement of efficient pulse-width gate-driver devices. Integrated enhanced planar transformers are a source electromagnetic disturbances due to inter-winding capacitances, which serve as route common-mode (CM) currents. This paper will simulate, via ANSYS Q3D Extractor, unforeseen parasitic effects pulse transformer integrated in SiC MOSFET card....

Capacitive diaphragm MEMS ultrasonic transducers are of great interest because they offer wide bandwidth and ready integration into arrays. However, fragility of these transducers is a significant barrier to their application. In this talk, we report on robust transducers which have been fabricated using the MUMPS process. The transducer design has been optimized to minimize stray capacitance b...

− Power distribution lines are a major source of interference in ECG recordings obtained with surface electrodes. Displacement currents coupled to electrodes, their leads and directly into the body, and stray capacitance in power supply transformers, result into differential-mode, common-mode and isolation-mode interference. Shielding electrode leads reduces displacement currents coupled to the...

The Soumi NPP VIIRS Day/Night Band (DNB) nighttime imagery quality is affected by stray light contamination. In this study, we examined the relationship between the Earth scene stray light and the signals in VIIRS’s calibrators to better understand stray light characteristics and to improve upon the current correction method. Our analyses showed the calibrator signal to be highly predictive of ...
