Wideband Mobile Antenna Design Using a Resonant Feeding Structure [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2022
Parallel loop feed structures can be used to implement wideband impedance. However, when a parallel loop feed structure is employed, parasitic resonance occurs in certain feed structures, resulting in the degradation of radiation efficiency.

Single, double and surround gate vertical MOSFETs with reduced parasitic capacitance [PDF]

open access: yes, 2004
The vertical MOSFET structure is one of the solutions for reducing the channel length of transistors under 50nm. Surround gates can be easily realised in vertical MOSFETs which offer increased channel width per unit silicon area.

Weak Capacitance Detection Circuit of Micro-Hemispherical Gyroscope Based on Common-Mode Feedback Fusion Modulation and Demodulation

open access: yesMicromachines, 2023
As an effective capacitance signal produced by a micro-hemisphere gyro is usually below the pF level, and the capacitance reading process is susceptible to parasitic capacitance and environmental noise, it is highly difficult to acquire an effective ...
