In this paper, a novel transformerless interleaved high step-down conversion ratio dc–dc converter with low switch voltage stress is proposed. In this converter, two input capacitors are series-charged by the input voltage and parallel discharged by a new twophase interleaved buck converter. Based on the capacitive voltage division, the main objective of the voltage-divider circuit in the conve...

In this paper, a low parasitic capacitance and low-power CMOS capacitive fingerprint sensor readout circuit is presented. The side effect of parasitic capacitance has been under control with novel layout structure in sensor cell, and minimal size switch is used to reduce non-ideal effects of MOS switch and achieve good linearity. Power dissipation is also reduced with quiescent current control ...

The high voltage alternating current transmission with submarine cables is the common scheme to integrate offshore wind farms close land. Due capacitive effect of AC cables, association long and onshore grid can cause resonances, which may amplify background harmonics. This paper focuses on mitigation harmonic amplification caused by farm integration. First, mechanism in integration system anal...

There has been considerable interest in recent years in using inductive storage techniques for pulsed power applications. Some of the advantages that inductive generators have over the more conventional capacitive systems include higher final stage energy density for higher power and smaller generators, lower insulator stress, faster pulse risetime, and the possibility of shorter pulse length. ...

ventriculoperitoneal (vp) shunt is one of the most common pediatric neurosurgical procedures. it has various complications that may have serious consequences such as shunt dysfunction, and unusual migration. although, migration of shunt catheter to bladder, heart, umbilicus, rectum, pulmonary artery, and stomach has been reported, migration to vagina is a rare one. in this report we present a 1...

Purpose The purpose of this paper is to study, a bridged-T topology with inductorless passive network used as bandpass (BP) negative group delay (NGD) function. Design/methodology/approach BP NGD under study composed an resistive capacitive network. circuit analysis elaborated from the equivalent impedance matrix. Then, analytical model C-shunt voltage transfer function established. considered ...

A new on-panel readout circuit with threshold voltage compensation for capacitive sensor in low temperature polycrystalline silicon (poly-Si) thinfilm transistor (LTPS-TFT) process has been proposed. In order to compensate the threshold voltage variation from LTPS process variation, the proposed readout circuit applies a novel compensation approach with switch capacitor technique. In addition, ...

In this work, we report a novel method for the dynamical control of the resonant electrical response of terahertz (THz) metamaterials. Our approach is based on planar arrays of split-ring resonators (SRRs) coupled with microfabrication methods to create a bimaterialcantilever-based THz metamaterial switch. Our device exhibits a tunable resonant response centered at 0.75 THz and operates by modi...
